OKX P2P order automation has a hard eligibility requirement: you must be a verified merchant or diamond merchant. Regular users cannot call P2P order interfaces even if they have a valid API key. The application review process takes up to 7 days, and only after approval can you use the API to replace manual operations for order processing, user inquiry replies, and systematic appeal handling. Official documentation covers reconciliation very limitedly, so you need to build your own matching logic based on order status and merchant backend records, instead of expecting a ready-made "reconciliation API".

Access: First confirm you are a qualified merchant
OKX's C2C API page clearly states the application eligibility: only verified merchants or diamond merchants can submit an application. This is not a "developer permission" issue, but a merchant identity issue. If you are a regular user and cannot see the API application entry on the P2P page, this is normal, not a problem with your account settings.
The application process itself is not complicated: submit your application on the P2P or C2C API page, OKX will review your merchant qualification and use case, and notify you of the result via in-app notification or email, with a maximum waiting time of 7 days. After the review is approved, you will get the permission to call P2P order related interfaces.
There is a confusing point to note: OKX's public API documentation (the /api/v5/ series) mainly covers spot, futures, account and other products. The P2P order API is not included in the public general API documentation system. You will get a set of dedicated interface permissions for merchants, instead of just checking a "P2P" permission box on the standard API Key creation page to get access. After your application is approved, OKX will provide the corresponding access guide or interface documentation, which is subject to the materials you actually receive.
What automation can do, and what it cannot do
According to the official description, the C2C API is positioned to "seamlessly connect your existing business system with the C2C market", and its supported features include batch order processing, customized transaction workflows, real-time reply to user inquiries, order status updates, and systematic appeal handling. These features correspond to the daily operations of P2P merchants, not market data acquisition or order matching.
In other words, API automation replaces the operation actions you perform in the merchant backend: automatic response after a user places an order, automatic status marking after payment, automatic workflow trigger when an appeal is submitted. It does not change the native rules of P2P transactions: you still need to confirm receipt of payment before releasing crypto, disputes are still handled by OKX support, and abnormal orders still require manual judgment. The API helps you execute these actions faster, but it will not take over your judgment responsibility.
One practical limitation: P2P transactions involve fiat payments, and the confirmation of fiat arrival in many scenarios depends on feedback from banks or payment channels. This information is not covered by OKX's API. Your automation system needs to connect to the payment channel's arrival notification by itself, or reserve a manual check step. OKX's API only covers order status and in-chat messages, and does not track whether the money has actually arrived in your bank account.
Reconciliation: No ready-made interface, you need to build it yourself
On all publicly available OKX official pages, there is no dedicated API documentation for P2P order reconciliation. The official description of reconciliation capabilities only stays at the level of "systematic appeal handling" and "order status update", and there is no interface that can pull full reconciliation details.
This means you need to design your own reconciliation logic based on the data you can get. A feasible approach is: use the API to get the order list and status changes, then match them with the arrival records from your payment channels. The key matching fields are order ID and amount, and the auxiliary fields are timestamp and counterparty information. P2P order receipts can be used as supplementary proof for reconciliation. Official notes state that receipts include real names of both trading parties, transaction date, amount, transaction type and payment data, and can be downloaded from the detail page of completed orders. If your automation system needs to keep proof files, you can trigger receipt download and archiving after an order is completed.
The completion standard for reconciliation is not "the API returns an order list", but "every P2P order marked as completed has a corresponding amount-matching arrival record on your payment side". The gap between these two data sources is the part that requires manual investigation: it may be caused by payment channel delay, amount mismatch, or abnormal order status. The API can help you narrow the investigation scope, but it cannot eliminate all gaps for you.
Alternative options if your application is rejected
If your merchant level does not meet the requirement, or your application is rejected, manual operation is still the only compliant path. Do not try to use a regular API Key to call unlicensed P2P interfaces, or look for so-called "P2P API cracks" or third-party proxy services. Such practices violate OKX's interface terms of use, and your merchant account is bound to real-name information and margin, so the risk is not worth taking.
A compromise automation direction is: only automate the parts outside the OKX platform. For example, use scripts to process payment channel arrival notifications, generate reconciliation tables, or use browser automation tools to assist with repetitive operations. Browser automation is not as stable as official API, but when you have not obtained merchant API permissions, it is the only option that does not violate the platform's interface rules. The downside is that it depends on the page structure, so your script may need to be updated when OKX revises its frontend.
One thing to confirm before you submit your application
The C2C API review targets "merchants", not "developers". What you need to prove in the application is your P2P transaction volume and merchant qualification, not your programming ability. If you are already a verified merchant, just submit your application and wait for review. If you are not a merchant yet, meet the merchant threshold first before considering automation. If you reverse the order, your application will most likely be rejected.
