Hey @vsi,
While the above mentioned endpoint still gives the gateway timeout error, I was able to make a successful request using the https://sandbox.api.connect.gov.bc.ca/auth/api/v1/orgs/:org_id/affiliations/:business_identifier. Which answered my question about businesses created in the sandbox being automatically affiliated with the account!
I had submitted a few business identifiers for enabling the affiliations testing using this support form and did not yet receive a confirmation about the update. But I noticed that the business identifiers I had submitted in the form had the passCodeClaimed: false property value and the others passCodeClaimed: true(which I assume is the default for businesses created using API system?). Does this mean that the businesses are ready for testing and if so, are there fake passcodes that can be used for creating affiliation for these business identifiers?

Thank you!
