Learn how to use the /orders/details/cars/terms-and-conditions endpoint to retrieve the full structured terms and conditions for one or more existing car rental orders.

| ✓ Post-booking | 3.2 Beta|

Use the /orders/details/cars/terms-and-conditions endpoint to retrieve the complete legal terms associated with confirmed car rental orders.

The response returns hierarchical legal content, organised into chapters containing nested sections, clauses, sub-clauses, and clause options. This structure is designed for rendering in user interfaces such as booking confirmations, vouchers, or order detail pages.

Use cases:

• Display full rental contract details to travellers.
• Show terms and conditions on order detail pages.
• Recreate the booking voucher terms section.
• Support legal and compliance requirements.

How it works

• You can provide up to 10 order IDs per request.
• The API returns a map of order IDs to their terms and conditions.
• Each order ID maps to either:
  • An object containing a terms field, or
  • null if the order ID is invalid or not found.

The endpoint supports partial success:

• Valid order IDs return their terms.
• Invalid or unknown order IDs return null.

Important notes

• Include at least one valid order ID.
• Provide booker.country to ensure correct legal and regional terms.
• Use filters.voucher: true to return only the subset of terms required for the booking voucher.
• The language field accepts a BCP 47 language tag (for example en-gb, es). If not specified or unsupported, the response defaults to English.

Request body

Example request:

{
  "booker": {
    "country": "gb"
  },
  "language": "en-gb",
  "orders": ["765255700", "invalid_order"],
  "filters": {
    "voucher": true
  }
}

Response structure

The response includes:

• request_id – Unique identifier for the request.
• data – A map of order IDs to their terms and conditions.

Data map behaviour

• Each key is an order ID from the request.
• Each value is either:
  • An object containing a termsfield, or
  • null if the order is invalid or not found.

Example:

{
  "request_id": "123456789",
  "data": {
    "765255700": {
      "terms": [ ... ]
    },
    "invalid_order": null
  }
}

Terms object

• terms – A hierarchical array representing the full rental agreement.
• Each node includes:
  • type (chapter, section, clause, sub_clause, clause_option)
  • Optional title
  • Optional children
• Leaf nodes (clause_option) contain the final displayable text in text.

Example response:

{
  "request_id": "123456789",
  "data": {
    "765255700": {
      "terms": [
        {
          "type": "chapter",
          "title": "Rental agreement",
          "children": [
            {
              "type": "section",
              "title": "Driver requirements",
              "children": [
                {
                  "type": "clause",
                  "title": "Age restrictions",
                  "children": [
                    {
                      "type": "sub_clause",
                      "children": [
                        {
                          "type": "clause_option",
                          "text": "Driver must be <b>at least 25 years of age</b> to rent this vehicle."
                        }
                      ]
                    }
                  ]
                }
              ]
            }
          ]
        }
      ]
    }

Best practices

✅ Validate input

• Ensure all order IDs in the orders array are valid strings.
• Invalid IDs return terms: null.

✅ Always include booker context

• Providebooker.country to ensure correct legal and regional terms.

✅ Use language for localisation

• Set language to match the traveller’s locale where possible.

✅ Voucher filtering

• Use filters.voucher:true when displaying only the terms required on the traveller’s booking voucher page.

✅ Render hierarchy correctly

• Preserve the nested structure when displaying terms.
• Only clause_option.text contains final displayable legal text.
• text may include basic HTML (for example tags). Ensure safe rendering or sanitisation where required.

Integration tips

• Treat the response as a tree structure, not flat content.
• Avoid flattening unless your UI explicitly requires it.
• Preserve ordering of all nodes when rendering.
• Use recursive rendering logic for best fidelity to legal structure.
