Sending letters via Pingen’s Post API is as easy as sending a standard email. Our API is digital and fully scalable.
Pingen automatically checks all submitted PDFs if they comply with the requirements of postal letters. If any requirements are not met, Pingen provides options to fix them directly via the API.
If the Deutsche Post or DHL fail to deliver any letters, they are automatically captured using the Pingen DMC, destroyed in a controlled manner, and reported via webhooks. This way, undeliverable letters are always processed digitally.
Pingen offers a staging environment to all developers to ensure that integrations are easily and conveniently tested in a sandbox. All features of Pingen are available in the sandbox but no letters will actually be sent.
Use the pricing calculator endpoint to check the price of a letter in advance. This way, you can always determine the full costs before sending any letter.
Pingen offers automatic notifications for important events via webhooks. For example, you will be notified immediately when a letter has been sent, has a problem or is undeliverable. This allows you to automatically take further actions without having to actively "poll" our API for changes.
In the webhook management of Pingen, you have access to detailed information for each request, such as the payload and the response from your system. This allows you to quickly identify problems and fix them with minimal effort.
The Pingen PHP Library offers everything you need to integrate our API and send letters via Deutsche Post and DHL. Pingen has already done the work for all PHP developers. Coming soon, we’ll release our SDKs for all other developers as well. 🚀
Our Post API offers much more than the classic API used by lettershops or mail service providers. With Pingen, you gain access to a fast-growing and international service that helps you send letters globally for the best price.
Already today, letters are being printed and sent locally in Switzerland, Germany, Austria, Holland and India.
Through our partnership with DHL, Pingen guarantees fast and reliable delivery to all other countries via air mail.
Pingen scales easily and is fail-safe due to our cloud and multi-site letter printing infrastructure.
With Pingen, you can also send letters via email, S3, Dropbox, Google Drive, OneDrive, or directly from services such as Odoo, ServiceNow, and more.
Thanks to our international presence and partnership with the Post and DHL, Pingen offers the fastest delivery at the most attractive prices.
