I will connect your apps with a custom API integration
Daniel G
About this gig
Move agreed data from one app workflow to another with a tested integration source package. You receive the code, automated tests, a configuration example and a clear setup guide. You install and configure the package in your own environment.
This gig covers one JSON webhook bridge: HMAC-SHA256 validation of incoming payloads, a defined flat field mapping and one destination using POST, PUT or PATCH. The destination must accept the delivered JSON request without additional authentication code. Source and destination compatibility must match this scope.
Choose your package by the number of fields to transfer. The tests check valid and invalid signatures, the expected transformed payload and a single forwarding request.
Work is AI-assisted. Send sanitized payload examples and the required output; never send passwords or API secrets. Live account setup, hosting, OAuth, Stripe-specific checkout or webhook handling, and ongoing maintenance are outside this package.

I build practical tools that reduce repetitive work and turn data into usable results. My focus is clean CSV files, public website datasets and clearly scoped integration code. You get written scope, example-based checks, clear files and straightforward handover notes. Work is AI-assisted and checked with automated tests. I work from files and written requirements, with all communication and delivery here on Fiverr.
FAQ
Will you log into my apps and activate the connection?
No. Delivery is tested source code and installation instructions. You configure and run it in your environment; live activation is not included.
Can this connect any two APIs?
Only sources and destinations compatible with the stated signed-JSON and request format. OAuth, provider SDKs and custom authentication require a separate, explicitly supported scope.
Does this include Stripe or ShipStation setup?
No. Those providers require specific authentication, event handling and tests. This generic webhook package must not be used as a substitute for provider-specific integration.
How are revisions handled?
Revisions cover the agreed field mapping or instructions within the same source/destination contract. New endpoints, authentication or features are new scope.
Which field names can I map?
Both source and output names must start with an ASCII letter or underscore and contain only ASCII letters, digits and underscores, up to 100 characters. The names __proto__, constructor and prototype are excluded. Hyphens, spaces and nested paths are outside this package.
