Payments and API integrations
I connect websites, stores and apps with Stripe payments, CRM, invoicing and other systems through REST APIs and webhooks. An example flow: a confirmed payment updates the order, triggers an invoice and grants access in the app. I define the source of each piece of data, the permissions of the connection and the behaviour on errors or when the same event arrives twice.
Let's talk about your projectWho is it for?
For companies that retype data between systems, want to accept online payments or need their own app connected to an external service. I check the API capabilities and permissions first, because they define the real scope of an integration.
What can we build?
- A data-flow description, field mapping and a decision on which system is the source of each piece of information.
- REST API connections and webhooks with authentication, for example OAuth, and an agreed permission scope.
- Handling of Stripe payments, orders, subscriptions, CRM contacts or documents in the invoicing system.
- Event verification, duplicate checks, retries and error handling, with the information needed to maintain the connection.
Tools chosen for the job.
We pick the stack to match your processes, your budget and the systems you already use.
How do we work?
- We map the process, the tools and the data that should move between systems.
- I review the documentation, test environments and available authentication methods.
- I build the connection and verify the happy path, errors and repeated events.
- After approval we configure the production environment and test the whole agreed flow.
Worth knowing.
Can any two systems be connected?
It depends on the available API, data export and service limits. Tell me the tools and the expected result, and I will check the possible connection and any scope limitations.
Do you implement Stripe payments?
Yes. I can connect payments with an app, orders or subscriptions. Before implementation we agree the sales model, access rules and the events the system should react to.
What happens when an external service stops responding?
We define the handling in the project. It can include saving a status, a controlled retry and a way to inspect the error. The choice depends on the API and on how important the process is to the business.
