send license challenge (assuming a generic license server SDK with no API front)

licence = requests.post(url, headers=headers, data=payload)
#print(license.text)
licence.raise_for_status()
l = response.json()['license']
print(l)

parse license challenge

cdm.parse_license(session_id, l)

print keys

for key in cdm.get_keys(session_id):
print(f"[{key.type}] {key.kid.hex}:{key.key.hex()}")

close session, disposes of session data

cdm.close(session_id)

this code is giving 400 error if you can correct it

I do not provide support for API fronts on License Acquisition Servers. This is likely some kind of authorization or mistake with the API calls. I will not provide support for this.
