Custom Substitution Parameters

In my last post I wrote about some custom context parameters that consumer.azurewebsites.net would send with every LTI request. After reading a discussion in the LTI forum, I decided to implement the additional context data available via custom substitution parameters. Specifically,

Substitution Description Example
$Context.stateId The state abbreviation AL
$Context.leaSourcedId The NCES ID for the LEA (e.g. school district) nces.ed.gov:4101920
$Context.schoolSourcedId The NCES ID for the school nces.ed.gov:410192000554

As a Tool Provider, you can request these custom parameters. For example,

The custom parameters that provider.azurewebsites.net requests.
