When I include cart\_items I get INVALID\_FIELDS - [CART\_ITEMS]: array(1) { [“status”]=\> array(5) { [“error\_code”]=\> string(29) “INVALID\_FIELDS - [CART\_ITEMS]” [“status”]=\> string(5) “ERROR” [“message”]=\> string(261) “The request attempted an operation, but one or more of the fields did not have a valid value. The request was rejected. Corrective action: Use valid values. The names of the affected fields appear at the end of the error code. See the API Reference for details.” [“response\_code”]=\> string(29) “INVALID\_FIELDS - [CART\_ITEMS]” [“operation\_id”]=\> string(36) “47bcd867-06de-4009-a467-eac8c8bb20b6” } } This is my code: ```auto "course", "amount" => 51, "quantity" => 2, ]; $body = [ "amount" => 102, "complete_checkout_url" => "https://...co.uk/sandbox/complete.php", "cancel_checkout_url" => "https://...co.uk/sandbox/cancel.php", "cart_items" => $cart_items, "country" => "GB", "currency" => "GBP", "merchant_reference_id" => "950ae8c6-76", ]; try { $object = make_request('post', '/v1/checkout', $body); // var_dump($object['data']['redirect_url']); var_dump($object); // header("Location: ".$object['data']['redirect_url']); exit(); } catch (Exception $e) { echo "Error: $e"; } ?> ``` ---

Thanks, @m2z, those fields are correct, and I made a generated a page in postman just to check. The URLs you have are actual URLs rather than …co.uk… correct? It would create an error if you input those specific strings (`https://...co.uk/sandbox/cancel.php`). My guess is the code is generating something, but cart\_items seems to have valid fields. **Request** ```auto { "complete_checkout_url": "http://test.co.uk/sandbox/complete.php", "country": "GB", "currency": "GBP", "cancel_checkout_url": "https://test.co.uk/sandbox/cancel.php", "merchant_reference_id": "950ae8c6-76", "amount": 102, "cart_items": [{ "name": "course", "amount": 51, "quantity": 2 } ] } ``` **Response** ```auto { "status": { "error_code": "", "status": "SUCCESS", "message": "", "response_code": "", "operation_id": "54cf6685-85b5-4eb7-a898-cff8dc9791bc" }, "data": { "id": "checkout_d3af1bd3147dcc93ef7af11b408c9de6", "status": "NEW", "language": null, "merchant_color": "323fff", "merchant_logo": null, "merchant_website": "http://rapyd.net", "merchant_customer_support": { "url": "http://support.rapyd.net", "email": "support@rapyd.net", "phone_number": "555-555-5555" }, "merchant_alias": "Test Business", "merchant_terms": null, "merchant_privacy_policy": null, "page_expiration": 1657657888, "redirect_url": "https://sandboxcheckout.rapyd.net?token=checkout_d3af1bd3147dcc93ef7af11b408c9de6", "merchant_main_button": "pay_now", "cancel_checkout_url": "https://test.co.uk/sandbox/cancel.php", "complete_checkout_url": "http://test.co.uk/sandbox/complete.php", "country": "GB", "currency": "GBP", "amount": 102, "payment": { "id": null, "amount": 102, "original_amount": 0, "is_partial": false, "currency_code": "GBP", "country_code": "GB", "status": null, "description": "Payment via Checkout", "merchant_reference_id": "950ae8c6-76", "customer_token": null, "payment_method": null, "payment_method_data": {}, "expiration": 0, "captured": false, "refunded": false, "refunded_amount": 0, "receipt_email": null, "redirect_url": null, "complete_payment_url": null, "error_payment_url": null, "receipt_number": null, "flow_type": null, "address": null, "statement_descriptor": null, "transaction_id": null, "created_at": 0, "updated_at": 0, "metadata": null, "failure_code": null, "failure_message": null, "paid": false, "paid_at": 0, "dispute": null, "refunds": null, "order": null, "outcome": null, "visual_codes": {}, "textual_codes": {}, "instructions": {}, "ewallet_id": null, "ewallets": [], "payment_method_options": {}, "payment_method_type": null, "payment_method_type_category": null, "fx_rate": null, "merchant_requested_currency": null, "merchant_requested_amount": null, "fixed_side": null, "payment_fees": null, "invoice": null, "escrow": null, "group_payment": null, "cancel_reason": null, "initiation_type": "customer_present", "mid": null, "next_action": "not_applicable" }, "payment_method_type": null, "payment_method_type_categories": null, "payment_method_types_include": null, "payment_method_types_exclude": null, "customer": null, "custom_elements": { "save_card_default": false, "display_description": false, "payment_fees_display": true, "merchant_currency_only": false, "billing_address_collect": false, "dynamic_currency_conversion": false }, "timestamp": 1656448288, "payment_expiration": null, "cart_items": [ { "name": "course", "amount": 51, "quantity": 2, "image": null } ], "escrow": null, "escrow_release_days": null } } ``` ---

@m2z, after speaking with a team member, it was pointing out that card\_items does need to be an array of objects vs an array of fields as referenced on [Checkout Page Object](https://docs.rapyd.net/build-with-rapyd/reference/checkout-page-object#custom-elements-object). ![Screen Shot 2022-06-28 at 2.10.13 PM](https://us1.discourse-cdn.com/flex016/uploads/rapyd/original/2X/9/957382414485e1df973dbbf35db2198bf0edba22.png) I’m unfamiliar with [PHP syntax](https://www.php.net/manual/en/language.types.object.php), What would your $cart\_items look like as an array of objects? ---

Your $cart\_items is an object, not an array of objects. It can be an array of one single object, but it must be the right datatype. ---
