## User story
As a SIMS team, we need to migrate off of GC Notify to the new BC notification service. This story is the early implementation to create the new notification service path.

## Acceptance Criteria
- [ ] Allow SIMS notifications messages to be send to a different notification API (BC Notify).
- [ ] Analysis to capture the expected adaptions in how messages are configured in SIMS and how to adapt them to use BC Notify.
- [ ] SIMS should be able to have GC Notify and a new provider (BC Notify) enable at the same time.
- [ ] Create a configuration to define the provider to be used for each message.
- [ ] A dynamic toggle can be used as a temporary configuration during the migration.

### Test and setup
- [ ] link CSTAR tenantID (see dev tools network tab when clicking on tenant) with Notify API key (API key in teams doc below)
- [ ] use postman environment and collection to bind api key to tenancy
- [ ] create a test template in Notify service to send an email to (templates to be managed in notify service below)

## Notes
- Per documentation below, for every environment
- API key must be requested for the Notify API
- Tenant requested in CSTAR.
- API key linked to Tenant ID (using postman collection)
- Templates to be managed in Notify service.
- Site URLs
- DEV API (manage key) - https://api.gov.bc.ca/devportal/api-directory
