FAQ
Why do I need to contact you before ordering your gig?
API integration is always custom, and every project has unique requirements. Contacting me first ensures I understand your project, confirm feasibility, and plan the best approach.
What information do you need to integrate an API?
Please share the API documentation and any credentials or access details before placing an order. Clear documentation helps me deliver faster and more accurately.
Can I add additional API sources from other applications?
Yes. You can provide additional APIs to integrate. We will review the requirements and confirm feasibility before starting.
Can you sign our NDA?
Yes. I can sign a mutual NDA. Please share it before starting the project.
What’s included in a revision?
Revisions cover fixes or adjustments related to the original API integration request only. New APIs, additional features, or unrelated changes are considered extra work.
What happens if the API is updated later?
I am available for updates and support. Any changes due to API upgrades will be handled after reviewing the new requirements and may require a custom offer.
