Which one, for what

APITemplate.io D

Good for Owners who need invoices, certificates, reports and social images filled from templates, with HTML, URL and Markdown to PDF on the same key and a choice of storage region.

Also in its favour

  • Free to start without a card

Watch for

One API key per account or team with no scopes or read-only mode, and GET /v2/delete-object deletes a file with a GET request

Canva REST APIs + MCP B

Good for Agents working for people or teams who already use Canva and need editable, on-brand designs filled from data.

Verdicts

APITemplate.io

A public OpenAPI description covers 12 operations, with rate limits, four regional endpoints and a 99.9 per cent uptime SLA published. Each account or team has one unscoped API key, no changelog or deprecation notices were found, the SDK repositories date from September 2023, and two documentation pages name different regional hostnames.

Canva REST APIs + MCP

OpenAPI 3.0 with 59 described operations, per-user rate limits and a 78-value error code enum. No server-to-server key, so unattended batch rendering has to run under one user's OAuth grant.

Before you call either

APITemplate.io

  1. Send the key in the X-API-KEY header and pick the regional host first, because requests and output are processed and stored in that region
  2. Call GET /v2/list-templates with with_layer_info=1 before POST /v2/create-image, so the name values in overrides match the template's elements
  3. Set meta to your own reference on each generation and check GET /v2/list-objects before retrying, since there is no idempotency key
  4. Set expiration in minutes (1 to 10080) or export_type=file for sensitive output. By default the download URL does not expire
  5. For async=1 you must pass webhook_url. The callback is a GET with the result in the query string, retried three times
  6. On HTTP 429 pause and retry on your own schedule. The docs give no Retry-After header or backoff interval

Canva REST APIs + MCP

  1. Call the user capabilities endpoint before autofill, brand templates or resize, which need Pro or above
  2. Poll export, upload and autofill jobs with exponential backoff and download results within 24 hours
  3. Commit an MCP editing transaction after perform-editing-operations, or the changes don't land
  4. Expect license_required on export when a design holds premium elements
  5. Read page_number, not the deprecated index, from Get design pages
