Invalid Timestamp Error at the Finance API in Germany (CSharp)

[md_layerworks]

I had an error 403 Forbidden for the Finance API

HTTP 403 Forbidden { "errors": [ { "errorId": 215113, "domain": "ACCESS", "category": "REQUEST", "message": "Invalid timestamp in signature parameters", "longMessage": "Invalid timestamp in signature parameters to fulfill the request." } ] }

All of my Changes are not working

Most of us here do not use the APIs, so I would suggest asking in one of the Developer sections of the forum where those who do use them will be more likely to be looking: https://community.ebay.com/t5/Developer-Forums/ct-p/developergroup

I'm thinking maybe this one specifically? https://community.ebay.com/t5/eBay-APIs-Talk-to-your-fellow/bd-p/eBayAPIs-Talk-to-your-fellow-develo...

Hi @md_layerworks,

This error typically occurs when the API's signature timestamp is incorrect or falls outside an acceptable range. Specifically, it indicates that the timestamp included in the signature parameters is invalid.

We recommend reviewing the section "5. Create the Signature-Input Header" in the documentation. Please ensure the timestamp in the request signature is correct and formatted according to the expected standards.

If the issue still persists, we kindly ask you to submit a support ticket through this link: eBay Support Tickets for assistance, which is a complimentary service. This will help us address your issue more effectively. Please provide API request, response including header details while submitting a support request. 

Additionally, please remember not to share these details here in the forum post, as they may contain confidential information that, if exposed, could lead to security concerns.

Best Regards,

eBay Developer Support
