Call Omnia APIs externally

1. Create an Omnia extension

   Lean how to create an Omnia extension

2. Generate a client credentials (a pair of ClientId/ClientSecret) for that extension.

   omnia secrets add --tenantid {tenantid} --extensionid {extensionid} --name {name}
   

   e.g.

   Run the below cmd to generate a secret for an extension on a tenant

   omnia secrets add --tenantid 9b0c2314-1a84-471a-8032-b547a66dc89e --extensionid 6bf14e2e-5636-4da8-8e00-5cde9709ecee --name CredentialForUsingInPowerAutomate
   

   Then you must save the output information, this is the only time the secret will be show.

   {
       "Name": "CredentialForUsingInPowerAutomate",
       "ExtensionId": "6bf14e2e-5636-4da8-8e00-5cde9709ecee", //ClientId
       "Value": "ysCKgSZ7CtIy6m6iSws6F3nOt9yPMQTi", //ClientSecret
       "CreatedBy": "",
       "CreatedAt": "2020-10-05T04:38:34.0119016+00:00"
   }

3. Add the client credentials to http request headers to be able to call Omnia APIs.

   Key	Value
   ClientId	extension id
   ClientSecret	a secret of the extension

   You should first call to your own Omnia extension APIs, then using other fx nuget. So that you can maintain the fx changes.
