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.
