My Business API: "Provided service type ID is not among those supported by the business's categories."

I am trying to patch a location with some new service types and I am using validateOnly set to true.

But the response I am getting is: "Provided service type ID is not among those supported by the business's categories."

I have been testing with different serviceId types such as:

gcid:parking_garage
gcid:parking_lot
gcid:parking_lot_for_bicycles
gcid:parking_lot_for_motorcycle

but to no avail.

Full error message is:

{
  "error": {
    "code": 400,
    "message": "Request contains an invalid argument.",
    "status": "INVALID_ARGUMENT",
    "details": [
      {
        "@type": "type.googleapis.com/google.rpc.BadRequest",
        "fieldViolations": [
          {
            "field": "service_items[0].structured_service_item.service_type_id",
            "description": "Provided service type ID is not among those supported by the business's categories."
          }
        ]
      }
    ]
  }
}

I am using the official PHP API client + service APIs as provided here:
https://github.com/googleapis/google-api-php-client-services

Official API reference:

• https://developers.google.com/my-business/reference/businessinformation/rest/v1/locations/patch?hl=en
• https://developers.google.com/my-business/content/services?hl=en

Any tips?

You misunderstood that documentation. The endpoint to get the categories will show you the available serviceIds per category if you request the FULL CategoryView (https://developers.google.com/my-business/reference/businessinformation/rest/v1/CategoryView).

To inspect available services for the given categories, a less cumbersome approach is to add them to a test location via the GBP UI and then execute a location get request and readMask set to serviceItems to inspect what the serviceItems array looks like for that location.

Added by the OP:
For anyone wondering about location object difference between location->categories->primaryCategory->serviceTypes (also for ->additionalCategories[x]) and location->serviceItems some info to clarify:

• location->categories->primaryCategory->serviceTypes seems to be readonly
  • and you just need to patch location->categories->primaryCategory (->additionalCategories[x]), format is similar to categories/gcid:wellness_center
• location->serviceItems are meant to be updated (patched) directly
  • format is similar to job_type_id:swimming for structuredServiceItem
  • and any string for freeFormServiceItem.
