Developer Marketing Microsoft 3651.0.0-beta.1

Preview a Microsoft 365 signature

Uses the employee resolver to preview one authorized sender and compose type. The response can include rendered HTML, text and the reason an assignment was skipped. Each connection has 30 previews per minute shared with the Portal.

POST/api/v1/marketing/microsoft-365/preview

Workspace automation for approved Dashio products. Each token is scoped to one Space and independently granted operations. Requests spend shared minute credits, and selected operation groups also share hourly quotas.

Required token scope is marketing:microsoft365:preview. Scopes are independent.

This operation uses 8 credits from a shared budget of 60 credits per token and 300 per Space each UTC minute. The rendering group shares 30 requests per token and 80 per Space each UTC hour.

Run these examples on a trusted server with DASHIO_API_TOKEN configured. Use a private terminal when inspecting response data. Examples send one request with a bounded timeout and do not retry automatically.
