I am using the form recognizer REST API and when I use cURL with the command line, I have no issue with the POST and GET requests as I am given the operation location from the POST output to then use in the GET request. However, I am trying to use the tool in bulk, and thus I am using the requests library in python. I am receiving the 202 accepted response, which as I've been reading online seems to be correct with this tool. The issue is that I am getting nothing back in the content of the request and thus I have now operation location to complete the GET request. Am I missing anything? Thanks for the help!
@fbald The analyze request is asynchronous i.e after the POST request the operation location is provided and the actual response from the analyze operation is stored in this location after the processing of form is complete. In your case if you are firing the POST requests in bulk and immediately using the operation location of all these requests in the GET then the result of the earlier response might not be updated at the location. Also, your pricing tier might also limit the transaction rate of your requests and some of the requests might get throttled or fail if these limits are exceeded.
To confirm, you could try to retrieve the operation result from REST API portal from one of your POST requests and this can confirm if your POST requests were successful to process the form.
The issue is that I am not receiving the operation location, even when I try with just one file. POST request is successful and I receive an operation location when I use REST API portal or cURL CLI. I am just not receiving the operation location to then complete the GET request with.
Also, if i have the correct operation location, my GET request is working just fine with correct output when using the requests library. I'm just not receiving the location from the POST.
@fbald Could you print the response.headers field? This should give you the operation location.

That is what I was missing. Thanks for the help!
hi fbald,
Here's a basic python script which includes a POST request.
Does this syntax help at all?
import requests
url = 'https://www.example.com/post'
payload = {
'key1': 'value1',
'key2': 'value2'
}
headers = {
'Content-Type': 'application/x-www-form-urlencoded'
}
r = requests.post(url, data=payload, headers=headers)
print(r.text)
This is along the lines with what I am doing, but r.text is just empty. I'm getting 202 accepted and there is text when I use cURL CLI.
@fbald What is the content-type header used? Is it application/json or application/x-www-form-urlencoded ?
I am using application/json
headers = {
'Content-Type': 'application/json',
'Ocp-Apim-Subscription-Key': azure_api_key,
}
params = {
'api-version': '2022-06-30-preview',
}
data = '{\'urlSource\': \'(form url)\'}'
response = requests.post('https://resource_name.cognitiveservices.azure.com/formrecognizer/documentModels/model_id:analyze', params=params, headers=headers, data=data)
print(response.text)
print(response.status_code)
print(response._content)
took out the specific names of the form url, resource name, etc. but this is the format I am using. Requests is already imported
