Steps
Generate an API key from account settings (app.optisigns.com/account-setting)
Call the GraphQL endpoint at graphql-gateway.optisigns.com/graphql (or use the web-based GraphQL IDE) with the API key for authorization, or install the official @optisigns/optisigns TypeScript SDK as a wrapper
Upload a file asset or create a website asset, scoped to a team_id (uploadFileAsset / createWebsiteAppAsset)
Query the devices list to find the target screen's device id (devices query or listAllDevices)
Assign content to the screen with the updateDevice mutation, setting currentType to ASSET or PLAYLIST and supplying the corresponding id (or call pushContentToDevice via the SDK)
Optionally push the change immediately (e.g., pushContentToDevice(deviceId, contentId, teamId, "NOW"))
Known gotchas
The underlying API is GraphQL, not plain REST — even the SDK's method calls map to GraphQL queries/mutations behind the scenes
Most asset and device operations require a team_id in addition to the resource id, which is easy to omit
List queries use cursor-based pagination (page.edges/node), not simple offset/limit params
