How to resolve “SOAP API” Error?

In Salesforce Marketing Cloud, a SOAP error signifies a problem with interactions through the SOAP API, which could stem from issues like incorrect request formatting, authentication failures, invalid data, server-side problems, or endpoint errors.

• Incorrect Request Format: The structure of the SOAP request might not be as expected by the API. This could be due to missing elements, incorrect namespaces, or formatting issues.
• Server Errors: There might be issues on the server side, such as temporary outages or configuration problems, causing the SOAP request to fail.
• Excessive API requests: The Marketing Cloud API blocking some calls when too many requests are made simultaneously. Since DESelect makes only a few API calls per selection, this could be related to other systems interacting with your SFMC instance.

How to resolve this?

• Check the Error Code and Message: Review the error code and message to understand the nature of the problem. The message can provide clues about what went wrong. For detailed information, consult the SFMC SOAP API Documentation and use the SFMC Error Codes Reference.
• Check Data Validity: Ensure that the data being sent in the request are accurate and match the expected format.
• Consider SF API Call Limit: Check if other systems are making API calls to SFMC and consider limiting them. Salesforce allows up to 2500 API calls per minute. You can reduce the scheduled running of Selections or scatter them at different times to not oversaturate the API calls.

If the problem persists after these checks, you might need to contact SFMC support for further assistance.
