Not Found error when charging Square API - square

Question

The Square REST API docs state that I should get a list of my locations and then use a returned location code when I call the transactions endpoint (to charge a credit card). I am doing exactly this but the returned error says that the merchant has no location with the supplied ID.
I have tried this with and without the location_id in the JSON sent to the transactions endpoint, since it is a path variable. Same result. I have also seen on Square's API FAQ that the usual cause of a 404 not found is the card nonce being created wrong, but this response clearly says the location ID is not valid.
I have tested this with Postman and JSON and I can see that the location code is correct. Here are my calls and the responses:
This is a GET request:
https://connect.squareup.com/v2/locations
And here is the response:
{
"locations": [
{
"id": "FPVPFZ4DXXXXX",
"name": "MyCompany",
"address": {
"address_line_1": "123 Candy Lane",
"address_line_2": "",
"locality": "Smithfield",
"administrative_district_level_1": "RI",
"postal_code": "02917",
"country": "US"
},
"timezone": "America/Los_Angeles",
"capabilities": [
"CREDIT_CARD_PROCESSING"
]
},
{
"id": "4FHNAN1WXXXXX",
"name": "MyCompany2",
"address": {
"address_line_1": "567 Smith Street",
"address_line_2": "",
"locality": "Greenville",
"administrative_district_level_1": "RI",
"postal_code": "02828-2910",
"country": "US"
},
"timezone": "America/Los_Angeles",
"capabilities": [
"CREDIT_CARD_PROCESSING"
]
}
]
}
I modified the returned IDs a bit in the above example.
Next I make a call to charge a card to this uri:
https://connect.squareup.com/v2/locations/FPVPFZ4DXXXXX/transactions
With this body:
{
"note":"",
"idempotency_key":"azsxdcfvrtrewsdf",
"location_id":"FPVPFZ4DXXXXX",
"shipping_address":{
"address_line_1":"123 My Street",
"address_line_2":null,
"locality":"Greenville",
"administrative_district_level_1":"RI",
"postal_code":"02828",
"country":"US"
},
"billing_address":{
"address_line_1":"123 My Street",
"address_line_2":null,
"locality":"Greenville",
"administrative_district_level_1":"RI",
"postal_code":"02828",
"country":"US"
},
"card_nonce":"CBASEPPW7fjdUHe-3jP6ZZ4kvE0gAQ",
"reference_id":"RT-12345678",
"amount_money":{
"amount":12500,
"currency":"USD"
},
"delay_capture":true,
"buyer_email_address":"jim#xxxxxxxxxx.net",
"customer_id":"JIM"
}
And I get this response:
{
"errors": [
{
"category": "INVALID_REQUEST_ERROR",
"code": "NOT_FOUND",
"detail": "This merchant does not have a location with the ID `FPVPFZ4DXXXXX`.",
"field": "location_id"
}
]
}
So the location ID matches exactly the ID returned by the locations endpoint.
Can someone familiar with this API help me out? Square's docs and support is sadly lacking.

I think the issue here is that you have tried to use your sandbox credentials (sandbox-sq0idp-defoUOlu...) to charge against your production location FPVPFZXXXXX. If you call ListLocations with your sandbox credentials, you should get a different location that you can then do sandbox charges with.
