Integration of payment service with Sales Force

Budget: 600 USD Deadline: 7 days

It can be done, but 70 USD here, in my opinion, does not cover a proper integration. Real work starts at around 600 USD - it depends on the payment service, the website, and how Salesforce is currently configured.

I would approach this not as a minor widget adjustment, but as a managed integration - webhooks from the payment system, status checks, recording data into the necessary Salesforce entities, error logging, and separate logic for subscriptions. This way, the system will not just pass fields but will properly control payments and renewals.

> Please clarify which payment system is used on the website and what the website is built on.
> What specific data should be sent to Salesforce - amount, client, tariff, payment status, renewal date, subscription cancellation.

Look, there’s a nuance here - if the payment system provides full events, the task can be done cleanly. If the widget is closed and lacks proper webhooks, we will have to look for a workaround, and that’s a different estimate =/ Expand

Adilzhan, the task is clear: we need to connect the payment widget with Sales Force so that parameters, payments, and subscriptions are correctly reflected and managed in the CRM. I have worked with web services, API integrations, and systems where statuses, synchronization, and data reliability are critical. First, I will quickly analyze the current scheme, then I will propose a secure option for integration and subscription control. I can discuss the details and start with an audit.

Hello. Do you have a custom-built website or is it on some CMS? I am ready to implement the integration.

Budget: 70 USD Deadline: 10 days

Integrating a payment widget with Salesforce: I will provide the necessary metadata parameters, payments, subscriptions, campaign/source data, and recurring logic so that Salesforce can see and control the operations.

Your main risk right now is that the payment goes through the widget, but Salesforce receives incomplete data about the client, campaign, or subscription, and then payments have to be manually reconciled between systems?

Budget and timelines will be discussed in private correspondence after reviewing the current widget, Salesforce logic, and webhook processing.

Hello, I worked on integrating the Stripe payment system with a CRM for an e-commerce project - I connected automatic synchronization of payments and subscriptions, which increased the conversion by 34%.

I am curious, which payment parameters are most critical to display in Sales Force - customer data, transaction statuses, or subscription analytics?

I suggest we get in touch; I will provide you with a free technical consultation and we can create a development plan + I will tell you about my team! ✨

Budget: 70 USD Deadline: 2 days

❤️Hi Adilzhan, I am very love this opportunity

I can help map all required payment parameters, connect the widget through API/webhooks, and sync customers, transactions, subscription status, renewals, cancellations, and failed payments into Salesforce. The implementation should keep Salesforce as the main control layer while maintaining secure payment handling and clean data flow.

My approach would include API integration, field mapping, webhook validation, error logging, testing with sandbox/live modes, and documentation so your team can manage payments and subscriptions confidently.

I can provide an accurate timeline after reviewing the payment widget and Salesforce setup.

Best regards,
Youssef.

Hello,

We can help you integrate your existing payment widget (TipTopPay) with Salesforce so that all required transaction and subscription data is properly synchronized and fully managed inside Salesforce.

With around 8 years of experience in backend development, API integrations, and CRM systems (including Salesforce environments), we specialize in building reliable and secure integrations between payment systems and business platforms.

Although we are new on this platform, we are not new to enterprise-level integrations and production systems.

Our understanding of the project

You currently have:

a payment widget embedded on your website
an existing Salesforce environment
a need to synchronize all payment + subscription data into Salesforce

Your key requirement is that:

all payments and subscriptions must be controlled and visible in Salesforce
all required metadata from the widget must be correctly passed and stored
data consistency between frontend payment system and Salesforce must be ensured
Proposed solution

We would implement a secure integration layer between the payment widget and Salesforce using API-based communication.

Key components:
capture payment events from TipTopPay widget
extract and map all required metadata parameters
send structured data to Salesforce via REST API
ensure correct object mapping (Contacts / Opportunities / Subscriptions / custom objects if needed)
implement webhook handling for real-time updates
add error handling + logging system for reliability
Subscription handling

We will ensure:

subscription creation and updates are properly tracked in Salesforce
payment status changes are synchronized (active, failed, canceled, refunded)
full traceability of transaction history inside CRM
Data integrity & security

We prioritize:

secure API authentication (OAuth / token-based access)
validation of incoming payment data
prevention of duplicate or inconsistent records
GDPR-compliant handling of customer data
Recommended approach

Depending on your Salesforce setup, we may use:

native Salesforce REST API
Apex classes / triggers (if required)
middleware integration (Node.js / PHP service layer)
webhook processing for real-time sync

We will select the simplest and most stable architecture for long-term maintenance.

Portfolio & next step

Instead of attaching generic portfolio examples, we prefer to discuss the exact integration structure first.

Budget: 350 USD Deadline: 5 days

Hello!

I have reviewed the documentation. The task is completely clear, and the logic of working with metadata and recurring subscriptions on the Salesforce side is transparent.

Since the integration architecture is fully isolated (mainly consisting of pure JavaScript for the widget in the browser and a separate PHP/Node.js script for secure token exchange with Salesforce), the engine of your site does not have a decisive impact.

However, for a clear division of responsibilities, I propose the following work format:

My part (Logic and API): I will fully develop the client-side JS scripts (validation, collecting URL parameters, forming the correct metadata object for TipTopPay) and the server script for secure authorization in Salesforce via the OAuth protocol. In the end, you will receive a fully functional, tested technical solution.

On your side (Interface implementation): If your site is built on builders or specific CMS (for example, Tilda or WordPress), placing the ready JS code into the appropriate design blocks and linking it to your specific buttons should be handled by your content manager or in-house developer who knows the specifics of setting up your template. Naturally, I will provide detailed instructions on where and which scripts need to be inserted.

The cost of my part (back + front logic): $350.
Timeline: 4–5 working days (including tests on your DEV Salesforce Scratch Org).

If this format of interaction suits you, I am ready to discuss the details of the integration. Expand

I will use PHP and the Salesforce API to integrate the payment system widget with the CRM system. To manage payments and subscriptions, I will create a REST API based on Salesforce. Power and control of payment processes through Salesforce. Details can be discussed in person.

Budget: 70 USD Deadline: 1 day

Hello!

Integrating payment widgets with CRM through API and webhooks is our area of expertise. We have carefully studied the technical specifications, and the task is completely clear: to pass the attribution through the metadata parameter TipTopPay so that Salesforce sees all parameters and manages payments and subscriptions on its side.

We see the implementation in three scenarios:

Face2Face (2 requests): on the backend, we obtain an OAuth token via Client Credentials, pull active agents and venues using an SOQL query, cache for 5–15 minutes, and send to the front end for picklists. On the form, we validate the entered agent_id against the uploaded list (inline error + block submit, without unnecessary calls to SF), venues through a closed picklist. The metadata includes agent_id, venue_id, plus campaign_id / source_code_id, if applicable.
Standard page (1 request): without lookups — we pass campaign_id (the name of the landing page) and source_code_id from ?source_code_id= into the metadata. We do not send empty keys — only actual values.
Recurring donations: the subscription is managed by Salesforce, not TipTopPay. We move the recurrent object from the request body into the metadata, add tokenize: true, so that SF charges according to the saved token on its schedule, and we do not create the built-in TipTopPay subscription (otherwise it cuts off the donor after 3 failures — which is not needed).
Salesforce reads the metadata back from the Pay webhook and links the donation to the necessary records — we will take this path into account and check it end-to-end.

Separately on security: Consumer Key/Secret and tokens are strictly kept on the server side, and do not enter the browser code. The credentials currently in the document should be reissued after transmission.

We will discuss details, access, and cost in private messages. Talk to you soon. Expand

Hello.

I have experience integrating payment systems, CRMs, and external APIs. According to the task description, it is necessary to connect the existing payment widget with Salesforce in such a way that all payment data, subscriptions, and related events are correctly transmitted and displayed in the CRM.

Budget: 100 USD Deadline: 1 day

Adilzhan, I will help connect the payment widget with Sales Force so that all key parameters, payment statuses, and subscriptions are transmitted and managed from the CRM. I have already integrated the API and established data exchange between the website and backend systems, so I will quickly understand your setup and propose a reliable solution. I can check the current widget, set up event transmission, and manage subscriptions through Sales Force. Shall we discuss the details?

Budget: 70 USD Deadline: 4 days

Good afternoon.

I have reviewed the technical specifications and the attached documentation. I understand the logic of integrating TipTopPay with Salesforce, including the transfer of metadata, OAuth Client Credentials, obtaining and caching lists of agents/locations, as well as processing recurring payments through Salesforce.

I have experience in PHP development, integrating REST APIs, CRM systems, payment services, and webhooks. Before starting the work, I will thoroughly study the current implementation of the site to ensure that the integration is carried out without disrupting the existing payment logic.

As part of the project, I am ready to implement:

• Integration of TipTopPay with Salesforce according to the provided specifications;
• Transfer of all necessary metadata parameters;
• Obtaining and caching agents and locations from Salesforce;
• Validation of Agent ID on the client side;
• Support for Face2Face and standard payment scenarios;
• Configuration of Salesforce-managed recurring donations;
• Testing, debugging, and support until full launch.

During development, I will maintain communication and regularly show intermediate results. After completion, I will provide a working solution and assist with deployment on the server.

I am ready to start immediately after receiving access and clarifying technical details.

Sincerely, David. Expand

Hello, do you have a website on a builder or is it custom-made? I will solve the problem quickly.

Budget: 70 USD Deadline: 1 day

Good day!

The task is clear — the TipTopPay widget is already installed, and we need to pass the metadata parameters (campaign_id, source_code_id, agent_id, venue_id) to Salesforce via the Pay webhook and link donations to the appropriate records (Campaign, Outreach Source Code, Gift Transaction).

According to the description, the work is divided into two parts: on the website side — correctly forming the metadata object depending on the type of page (regular / Face2Face / recurring), for F2F — adding a server request to Salesforce OAuth to obtain agents and venues. On the Salesforce side — processing the incoming webhook and mapping the fields.

I have experience with custom integrations of payment systems (LiqPay, WayForPay) and REST API on the WordPress/PHP side. I have already studied the structure of metadata and the logic of the scenarios.

A few questions for accurate assessment:
- What is the website built on (WordPress, custom, other)?
- Is there already a webhook handler on the Salesforce side, or does it also need to be created?
- Which scenarios are a priority — standard page, F2F, or recurring?

I will respond regarding timelines and costs after clarifying the stack. Expand

Hello. I have experience integrating payment systems with CRM and external APIs.

Hello.

I can integrate the TipTopPay payment widget with Salesforce so payment metadata, customer details, transaction status, subscription status, and required business parameters are visible and controlled from Salesforce.

I would not just “send data” once.

I would set up a clean payment flow where the widget passes the correct metadata, TipTopPay webhooks update Salesforce in real time, and Salesforce becomes the main place to track payments, subscriptions, retries, cancellations, and status changes.

I can map the required fields, create or update Salesforce records through API, handle successful and failed payments, sync recurring subscription events, and add logging so missed or failed syncs can be checked safely.

Before implementation, I would like to confirm one thing.

Do you already have Salesforce custom objects for payments and subscriptions, or should I create the structure for them as part of the integration?

As far as I understand, all payments from the widget also need to be added to the SalesForce CRM? Can you show me the website?
