Help with API connection to Xero oAuth 1.0

Help with API connection to Xero oAuth 1.0

  

Hi everyone,

I'd like to connect my OutSystems app to Xero using oAuth 1.0

I tried to get some inspirations from all of the links below but I haven't been able to adapt it to my needs with Xero:
- https://www.outsystems.com/forge/component/129/twitter-connector/
- https://www.outsystems.com/forge/component/446/oauth-connectors/
- https://devblog.xero.com/de-mystifying-oauth-1-0a-with-postman-66cb257da7d9


All I would like to do is to Post invoices to Xero.
I don't even mind using Zapier if this can ease the integration.

I'm currently stuck in the oAuth 1.0 authentication   


Thanks a million if you can help and please let me know if you need more information.

I'm getting close with this error message:

oauth_problem=signature_invalid&oauth_problem_advice=Failed%20to%20validate%20signature


Now I need to know how to create this signature using SHA1


Help? Anyone? ^^

Hi Melwyn,

When you are integrating Xero API with outsystem, this error come because you are not using token key & secret key. In Xero, when you call main xero api to get/put/post method before that you need to call 3-4 api just to know token key, scret key etc.
