What is the API used for the most?

The API is mainly used for accounting and ERP integrations that pull in data from Payhawk on a periodic basis or in real time. The data can include expenses, bank statements including all the fields such as amounts, VAT rates, categories, descriptions, custom fields, etc. The API can also be used to update data, such as custom fields.

Yes, the API is free to use for all Payhawk accounts.

Is there request throttling or limitations of the API?

The API is limited to 15 requests per second, which should be suitable for all use cases.

Where can I find the API key?

The key can be found in the Payhawk Portal under Account -> Settings. If the key is not yet activated, contact us at partners@payhawk.com.

What is the main API URL?

The URL is https://api.payhawk.io/api/v3. The rest of the path is then added, depending on the requests, for example, expenses - /api/v3/accounts/{accountId}/expenses.

Do you support webhooks and can they be used to create real-time integrations?

Yes. The full list of webhooks can be seen [in the documentation](https://developers.payhawk.io/) under IWebhookSubscription -> eventType

How does the pagination work?

By design, we return up to 1000 items per request to avoid timeouts. To request the next 1000, use the skip and take parameters.

Can I create or review expenses via the API?

These functionalities are not available through the API. The user, not the system or an accountant, should perform actions such as creating an expense. The API actions are performed on behalf of the system.

Payhawk is renowned for offering cutting-edge card, expense, and spend management solutions, all seamlessly integrated with NetSuite. We first became customers of Payhawk and quickly realised the potential it had for our own clients. The quality of the native integration with NetSuite is perhaps the greatest strength, which means no complex reconfigurations at setup, easy customisation of fields and categories, and real-time two-way syncing of data.
