I will build or fix rest api integrations and webhooks in python
Alexander B
About this gig
Need two apps to exchange data, or an existing API connection to work again? I will build or repair one clearly defined data flow in Python.
Examples include sending a form event to your CRM, retrieving API data for a report, or passing an order event to an existing system.
The $100 package covers:
- One source endpoint or webhook event to one destination action
- Up to 10 mapped fields, using existing API-key or Bearer-token access
- A successful sample transfer and a relevant failure test
- Duplicate-event handling where the agreed destination supports it
- Source code, configuration instructions and a short handover note
Delivery: 3 days, 1 revision to the agreed flow. The code runs in your agreed environment. An always-on webhook needs existing suitable hosting; hosting and provider fees are not included.
Send the API documentation, sample input, expected result and current error if any before ordering. I will check feasibility and confirm scope. New OAuth apps, payment flows, dashboards and multi-step integrations require a separate quote.
Everything can be handled in Fiverr messages. No call needed.

FAQ
What does one connection include?
One source endpoint or webhook event, one destination action and up to 10 mapped fields. We agree the exact input, output and tests before ordering.
Can you fix an existing integration?
Yes, after I can reproduce the issue and confirm it fits this package. Account recovery, unavailable providers and a full system redesign are not a one-flow repair.
Where will the code run?
In one agreed environment you control. A manual API script can run locally. An always-on webhook requires suitable hosting and an accessible endpoint before work starts. Hosting and API fees are separate.
Can you work with OAuth or payment APIs?
These need an individual scope. Basic assumes working API-key or Bearer-token access and does not include a new OAuth application or payment implementation.
How do you avoid duplicate records?
We agree an event or record key and a duplicate-handling rule. I test repeat delivery when applicable and disclose any destination limitations before accepting the order.
