Hi @Abdul_Waheed,

From the error response, this may be due to a couple things:

1. All spaces and other whitespace outside of strings must be removed.
2. Numbers should be sent in strings, not as integers/numbers.

Here are some resources that may help:

- [Rapyd API Request Signatures and How to Calculate](https://community.rapyd.net/t/rapyd-api-request-signatures-and-how-to-calculate/1256)
- [Verify Webhook Signature? - #2 by Minh\_Nguy\_n\_Van](https://community.rapyd.net/t/verify-webhook-signature/1383/2)

I would also take a look around your body and and how it may not be parsed correctly.
