I am receiving "Error: unable to verify the first certificate" when adding/removing users to custom study groups. I am checking now to see if the error is on my end, but I haven't changed anything.

We do not see this ourselves. We did update a security certificate. Try restarting your browser and clearing your browser's cache.

The control panel on Sierra Chart works fine for adding/removing users. The API no longer works. I am still having the same error this morning.

You are referring to the API itself. Not the webpage. We will check on that.

How are you accessing the api?

I get errors making the request locally on Postman (just a way to send requests) as well as through my automated implementation running on a server.

obviously changed the variables curl --location --request POST 'https://www.sierrachart.com/API.php?AdminUsername=enterusername&AdminPassword=enterpassword&Service=CustomDLLStudiesManagement&SCDLLName=TPH%20Custom%20Studies&Action=add&UserSCUsername=entergiveusername' |

We have tested curl, and we do not see the stated issue. Can you confirm that your computer clock is set correctly? curl -I 'https://sierrachart.com/API.php'

We do see that there was an issue with the following version of curl 7.81.0. So at the moment we have reverted to the older cert which fixes the issue. We will need to see why the new certificate does not work with older version of curl. Sierra Chart Support |

Yes it is. - I should clarify that when running curl from terminal the error is actually "ERROR: SCDLLName not set" but it very clearly is set. When i make the request in Postman you can see the certificate error (attached image) which is also what the implementation on the server returns. |

The curl command in post 9 is not setting the SCDLLName properly. Note the the documentation specifies it to be sent as a post, but you are sending it as a get (part of the URL). To send data as a post you need to use -d with curl https://curl.se/docs/manpage.html#-d Sierra Chart Support Date Time Of Last Edit: 2024-05-17 17:22:01

To add on here, there are API errors from Python as well where requests does not work, but urllib3 does. requests gives SSL errors unless you turn off verify (strongly discouraged of course!). NOTE: looks like your form/site is trying to make the "CODE" with a Sierra URL into a link. previously worked now broken: with requests.Session() as session: for sierra_dll in sierra_dlls: if True: url = 'https://www.sierrachart.com/API.php' payload = { 'AdminUsername': username, 'AdminPassword': password, 'Service': 'CustomDLLStudiesManagement', 'SCDLLName': sierra_dll, 'Action': 'GetAllUsersForDll' } # Use the post method to send a POST request !!!broken response = session.post(url, data=payload) !!!workaround response = session.post(url, data=payload, verify=False) this code works and must use some different cert chain verification: http = urllib3.PoolManager() resp = http.request( 'POST', 'https://www.sierrachart.com/API.php', fields={ 'AdminUsername' : username, 'AdminPassword' : password, 'Service' : 'CustomDLLStudiesManagement', 'SCDLLName' : sierra_dll, 'Action' : 'GetAllUsersForDll', } ) json_data = json.loads(resp.data) |
