"csv_import" ERROR: No database/alias specified

[UnLuckiestClovr]

When working with "csv_import" for a website I am helping code, I ran into an issue with the CSV Importing, whereas I am able to call to the endpoint I get a "ERROR: No database/alias specified" response. I do not know what I might be doing wrong, as I thought I had everything solved. I checked the documentation, 49u is what I had, and could not find any mention of this error or field. Attempting to add said parameters via the URL "?parameter=<value" did not yield any results.
Parameters used:

method: csv_import
account:
username:
password:
data: <utf-8 encoded, base64 formatted CSV file>

https://service.sheltermanager.com/asmservice?method=csv_import&account=&username=&password=&data=

I am going through the "sheltermanager.com" database, so I do not know if that effects what I am doing.

Any help would be appreciated as this is a time sensitive matter.

The error is saying that the account parameter you have passed isn't valid. It needs to be the account number or alias for the sheltermanager database you want to access via the service.

Weird, the account parameter I am using works with the other endpoints. Why would it be different with this one?

[bobintetley]

The parameters can only be read from one method, so if you are POSTing the data, you need to POST the data as URLencoded with all the parameters, or you need to do a GET, passing all the parameters.

You can't mix them by including account/username in the query string and the data in the post body. Maybe that's what you're doing?

I originally tried setting up the data in the body as
{
"data" : "",
"encoding": "utf-8"
}

That kept returning issues with 500 errors that did not hold error messages.

I swapped to a URL setup using url parameters and stopped getting those 500 errors and instead got the

Code:200

Response: ERROR: No database/alias specified

I obviously can't show the full url for security, but I can give an example:

https://service.sheltermanager.com/asmservice?method=csv_import&account=OUR_ALIAS&username=USERNAME&password=PASSWORD&data=LONG_ENCODED_STRING_FOR_CSV

Which led me to where my team is now. With this response.

This same account alias works on every other ServiceAPI call we have tried so far.
I thought it might be an issue with using POST but we ran into a massive error when any sort of json body was attached, but when running without a body I recieve an error based on the output.

POST: 200 | ERROR: No database/alias specified
GET: 500 | Permission Error - Forbidden

The post data in the body must be URL encoded. Eg: account=A&username=X&password=Y&method=csv_import&data=[BASE64...]
