curl

curl \
  -H "Authorization: Bearer $BUEZLI_API_TOKEN" \
  "https://api.buezli.app/2026-07-14/schema"

Request JSON explicitly when your client does not send an Accept header. Successful responses use data; collections also include meta.pagination.

curl \
  -H "Accept: application/json" \
  -H "Authorization: Bearer $BUEZLI_API_TOKEN" \
  "https://api.buezli.app/2026-07-14/clients/123"

Use page and limit to move through collections. limit accepts values from 1 to 100.

curl \
  -H "Authorization: Bearer $BUEZLI_API_TOKEN" \
  "https://api.buezli.app/2026-07-14/clients?page=2&limit=50"

Pass updated_since to retrieve later changes. Archived records include _deleted: true so a sync can remove them.

curl \
  -H "Authorization: Bearer $BUEZLI_API_TOKEN" \
  "https://api.buezli.app/2026-07-14/clients?updated_since=2026-07-14T10:00:00Z&limit=100"

Use expand when you need related records in the same response. Invoice and estimate line items are included by default.

curl \
  -H "Authorization: Bearer $BUEZLI_API_TOKEN" \
  "https://api.buezli.app/2026-07-14/time_entries?expand=client,project"
