[Bug]: Can't query transactions with users, payment types or types in parameters, same as #322

[pabloriquelmecas]

What happened?

As discussed on Issue #322, it is not possible to query transactions filtering for a user, it throws an error

merchant = "merchant_code"
client = Sumup(api_key="API_KEY")
result = client.transactions.list(merchant_code=merchant,users=["user@mail.tld"])

Traceback (most recent call last):
  File "<pyshell#13>", line 1, in <module>
    result = client.transactions.list(merchant_code=merchant,users=["user@mail.tld"])
  File "C:\Users\Pablo\AppData\Local\Programs\Python\Python313\Lib\site-packages\sumup\transactions\resource.py", line 327, in list
    raise APIError(
sumup._exceptions.APIError: The request is invalid for the submitted query parameters.

The line with the problem is not beign fixed on the latest release #302

sumup-py/sumup/transactions/resource.py

Line 261 in 06e0cc1

query_data["users[]"] = list(users)

I can query without a problem the transactions with the statuses parameter, entry method, changes_since, newest time and oldest time, can't query with payment types and types.

merchant = "merchant_code"
client = Sumup(api_key="API_KEY")
result = client.transactions.list(merchant_code=merchant,types=["PAYMENT"])
Traceback (most recent call last):
  File "<pyshell#33>", line 1, in <module>
    result = client.transactions.list(merchant_code=merchant,types=["PAYMENT"])
  File "C:\Users\Pablo\AppData\Local\Programs\Python\Python313\Lib\site-packages\sumup\transactions\resource.py", line 327, in list
    raise APIError(
sumup._exceptions.APIError: The request is invalid for the submitted query parameters.

merchant = "merchant_code"
client = Sumup(api_key="API_KEY")
result = client.transactions.list(merchant_code=merchant,payment_types=["ECOM"])
Traceback (most recent call last):
  File "<pyshell#34>", line 1, in <module>

Hi! Thanks for reporting.

After further investigation, this seems to be an actual bug in the API handling this specific endpoint. The API isn't fully spec-compliant when it comes to handling of query params, i.e. doesn't respect query encoded characters such as users%5B%5D=email@example.com (equivalent of users[]=email@example.com).

I have opened a PR on the upstream service and will let you know once the team gets back to me.

Hi @pabloriquelmecas, we have merged a fix on the service itself. I have tested it locally on latest main and it works. Please let us know if you have any more issues.

Hi @matoous , the issue is fixed, I have tried with every parameter that was failing and everything is ok, thanks for your help
