How to add OAuth Authentication in SOAP API's in VB.Net ?

Hi Priya,

Since you already have your SOAP APIs developed and to obtain the bearer token, you can achive it in the following way.

Obtain the Bearer Token:
1. Call the OAuth Token Endpoint: Make a REST API call to the OAuth token endpoint to obtain the bearer token. You'll need to provide the appropriate credentials (client ID, client secret, etc.) and grant type (e.g., client_credentials).
2. Example Request: Something like this you need to add to get the bearer token.

POST /oauth/token
Host: auth.example.com
Content-Type: application/x-www-form-urlencoded

grant_type=client_credentials&client_id=your_client_id&client_secret=your_client_secret

2. Use the Bearer Token to Access SOAP APIs: Now you can include the Bearer Token in SOAP Requests. Modify your SOAP API requests to include the bearer token in the Authorization header.'

Example SOAP Request: Something like this.

POST /soap/api
Host: api.example.com
Content-Type: text/xml; charset=utf-8
Authorization: Bearer your_access_token

After getting the bearer token, you can now use it in your existing application.
