API test : error "SAML2 service not accessible"

[Thomas_Dautrey]

Dear all,

I am working on the integration part of our S4HC implementation project.
I have activated some APIs in S4HC and I used to try them through web browser or Postman tool.
This was working well, but since few days it does not anymore.

I have the following message :

It looks like an authorization problem, but the authentication method to access the APIs is "User ID and Password". And the User ID and Password provided are OK.

Do you know how to solve this?
Many thanks for your help.

Best regards,
Thomas DAUTREY

Hi,

You can add "?saml2=disabled" on your URL in order to disable the SAML and use the user/password authentication.

your URL is missing the -API, use

my301057-api.s4hana.ondemand

for API requests, then there is no SAML request anyways
