- Existing webhook and API troubleshooting
Choose your package:
Basic: 1 API endpoint or webhook connection.
Standard: Up to 3 API or webhook workflows.
Premium: Up to 6 advanced API workflows with integrations.
I work with documented APIs and supported authentication methods.

FAQ
Do you need API documentation before starting?
Yes. Please share the relevant API documentation, endpoint details, authentication requirements, and expected data flow. I can review these before ordering to confirm feasibility and scope.
Can you create and troubleshoot webhook integrations?
Yes. I can configure supported incoming and outgoing webhooks, map payload data, trigger workflows, and troubleshoot common webhook delivery or processing issues.
Can you work with API keys, bearer tokens, and OAuth?
Yes. I can configure supported API key, bearer token, and standard OAuth connections. Complex OAuth implementations, app verification, or custom authentication flows may require a separate quote.
Which automation platforms do you use for API integrations?
I work with Make, Zapier, n8n, and supported HTTP or API modules. I'll recommend an appropriate platform based on the API capabilities, workflow requirements, and your existing tools.
Can you integrate an application that has no public API?
It depends on whether the application provides a supported integration method, webhook, export feature, or authorized alternative. I don't guarantee integrations with undocumented or restricted APIs.
Will you include error handling and testing?
Yes. Every package includes testing. Standard and Premium packages also include error handling appropriate to the agreed scope, such as handling failed requests, invalid responses, or supported retry behavior.
Are API usage and automation platform costs included?
No. API usage fees, software subscriptions, hosting, and automation platform charges are paid separately by the buyer.
What is included in a revision?
Revisions cover adjustments to the originally agreed endpoints, field mappings, and workflow logic. Additional APIs, endpoints, applications, or major feature changes may require a separate quote.
