PayTabs Support Portal

Welcome, Dear Rani,

Thanks for reaching PayTabs out on our Developers Community. My Name is Osama El-Hamahmy the technical support team and I will be looking into this post and following up with you.

This error probably happened because the PayTabs system failed to authenticate/identify the sent request information from your side. it seems that either you passed the wrong integration keys, or you did pass an invalid profile id or API endpoint. To know more about this, Please check our  (E): Authentication failed. Check profile ID and authentication header solution article.  You may also check  How to get my Authentication/Integration/API Keys? and How to get your account information from PT2 Dashboard? solution articles.

I hope this resolves the confusion you have.

You should also know that we are providing you with a great "Solutions Portal" that includes so many articles that can walk you through any situation such as the "The How to & The What Is (FAQ)" category which contains the technical and non-technical FAQ, and the "How to Integrate with PayTabs?" category which contains all the available methods to integrate with the fully detailed documentation and "Troubleshooting Your Issues/Errors" category which will allow you to trace and solve your issues without seeking for any assistance.

Please don't ever hesitate to comment back if you still have further inquiries.  Let me know if there's anything else I can help with.

Glad to be always in help.

Hoping you have a profitable and successful trade.
