FIX API Logon Troubleshooting.

Artur Pietrzyk

This article will contain the most common issues related to the initiating FIX connection:

Make sure you have Professional level subscription or you have the FIX access provisioned on your API Key
Use our configuration for the initiator and the FIX44.xml file from our GitHub repository (https://github.com/coinapi/coinapi-sdk/tree/master/csharp-fix)
Make sure that your API Key in initiator config is correctly pasted into SenderCompID key.
Check the value of the TAG=52 in the LOGON (A) message. Time should be in the UTC timezone and it can't differ too much from the actual time.
