I will connect custom API webhooks and json payloads in make com or integromat


About this gig
Does your software lack a native integration on Make.com or Zapier? Don't let that stop your business. I will build custom API connections to link any platform with an open API documentation into your automated workflows.
I specialize in handling advanced technical setups on Make com (formerly Integromat). If your workflow requires custom HTTP modules, secure webhooks or complex JSON data parsing, I can configure a stable, scalable pipeline that passes data flawlessly between your apps.
What I can handle for you:
- Connecting custom REST APIs using Make's HTTP modules
- Setting up OAuth2, API Key and Bearer Token authentication
- Creating custom instant Webhook listeners to capture real time data
- Parsing complex JSON payloads, nested arrays and data collections
- Resolving data mapping, formatting and structural API errors
- Syncing custom internal company databases with external SaaS tools
Why choose this gig?
As an automation engineer, I understand raw backend data structures. I don't just use drag and drop apps, I build custom bridges using Postman and clean API protocols to make sure your automation never drops a single lead or transaction.

FAQ
What do you need from me to connect a custom API?
I will need the public API documentation link of the software you want to connect, your login credentials/API keys for that platform and a clear explanation of what data you want to send or receive.
Can you work with APIs that require secure OAuth2 authentication?
Yes. I can configure custom headers, query parameters, and multi step authorization requests inside Make's HTTP module to safely authenticate your account.
What is JSON parsing, and why do I need it?
Many custom tools output data in a raw code format called JSON. I use Make's built in JSON parser to turn that raw code into clean text fields (like Name, Email, Price) that your other apps can read and use.
Do you write custom code if the API is too complex?
If required, I can use Make's Javascript tools or advanced data functions to manipulate text, format dates, and split arrays to match your target platform's database structure.
