How to fix 403 error when creating GoogleFit datasource-CodePudding

I am using GoogleFit Rest API to create a nutrition data source so that I can subsequently store nutrition information. I have done this successfully on Android via the GoogleFit SDK, but because no such SDK is available on iOS, I resorted to using the REST APIs via the link above. When trying to create the data source I am returned the following error:

{
    "error": {
        "code": 403,
        "message": "The caller does not have permission",
        "errors": [
            {
                "message": "The caller does not have permission",
                "domain": "global",
                "reason": "forbidden"
            }
        ],
        "status": "PERMISSION_DENIED"
    }
}

and the POST request I am using is:

Endpoint: https://www.googleapis.com/fitness/v1/users/me/dataSources

Body:

{
    "application": {
        "detailsUrl": "https://strongfoundation.dev",
        "name": "Strong Foundation",
        "packageName": "com.coding.casa.Strong.Foundation",
        "version": "1.0.1"
    },
    "dataStreamId": "raw:com.google.nutrition:com.coding.casa.Strong.Foundation:Apple:iPad Air (3rd generation):****",
    "dataType": {
        "name": "com.google.nutrition"
    },
    "device": {
        "manufacturer": "Apple",
        "model": "iPad Air (3rd generation)",
        "type": "phone",
        "uid": "*****",
        "version": "15.7"
    },
    "name": "strong-foundation-food",
    "type": "raw"
}

Has anyone seen this error and was able to resolve it? I have tried adding the API Key to the request, but that did not change the error, and I do have the Fitness API enabled on my project.

EDIT:

I am also supplying a Bearer token with the following authorized scopes

    "https://www.googleapis.com/auth/fitness.activity.read",
    "https://www.googleapis.com/auth/fitness.body.write",
    "https://www.googleapis.com/auth/fitness.body.read",
    "https://www.googleapis.com/auth/fitness.nutrition.read",
    "https://www.googleapis.com/auth/fitness.nutrition.write",

CodePudding user response：

You don't include the others details of the REST method call.

Importantly, HTTP 403 is Forbidden suggesting that you didn't include an Authorization header in your request with value Bearer {TOKEN} where {TOKEN} is an access token for an identity that has suitable scopes to access the API. See authorization

Although Swift is not one of Google's officially supported languages, Google has a Swift REST Client Generator for Google APIs and you should be able to use it to generate a Google client library for Swift for Google Fit.

CodePudding user response：

Did some more playing around with the FitnessAPI (specifically creating data sources) and found the issues was with my request payload.

The payload that worked for me is as follows:

{
    "application": {
        "detailsUrl": "https://strongfoundation.dev",
        "name": "Strong Foundation",
        "version": "1.0.1"
    },
    "dataType": {
        "name": "com.google.nutrition"
    },
    "device": {
        "manufacturer": "Apple",
        "model": "iPad Air (3rd generation)",
        "type": "phone",
        "uid": "****",
        "version": "15.7"
    },
    "name": "strong-foundation-food",
    "type": "raw"
}

The deltas from the original one are removed the following properties:

application.packageName
dataStreamId
