Create contributor invitations for a card

Create contributor invitations for a card.

Use this after creating a card when you want to invite contributors by email, SMS, or group.

Typical flow:

1. Create or locate a card with POST /api/cards or GET /api/cards.
2. Submit one or more invitees to this endpoint.
3. Use GET /api/cards/:card_id/invitations to inspect invitation records.
4. Use POST /api/cards/invitations/resend if you need to resend a specific invitation later.

Example:

curl -X POST "$BASE_URL/api/cards/invitations" \
  -H "Authorization: Bearer <access_token>" \
  -H "Content-Type: application/json" \
  -d '{
    "card_id": "<card_id>",
    "title": "Please sign Jordan's card",
    "message": "Add your note before Friday.",
    "invitees": [
      {
        "delivery_type": "email",
        "delivery_id": "[email protected]"
      }
    ]
  }'

Authentication for this endpoint requires this header:

• Authorization: Bearer <access_token>

Generate the bearer token by:

1. rotating credentials at POST /account/api-access/credentials/rotate
2. exchanging them at POST /account/api-access/token
