# <FAQ /> FAQs

## Do you offer API support? {#faq-api-support}

Yes! We provide robust API support, enabling seamless integration of our e-signature capabilities into your products
or applications. Our dedicated API support team, kick-off calls, and assigned developer experts ensure a smooth
experience.

## Can I test the API for free? {#faq-free-testing}

Absolutely, API customers have the opportunity to thoroughly test Blueink's API at no cost. There's no time limit for
API testing, ensuring you can assess the API's performance and features at your own pace. 

On an API Trial account, you are limited to sending Bundles in "test mode" (where `Bundle.is_test` is set to `true`).
These Bundles can be sent to verified email addresses in your account.

When testing or building out your integration is complete, you can purchase production API Envelopes
to start sending live Bundles / Envelopes, without test limitations.

## Can I Send non-API Bundles when I sign up for an API Plan? {#non-api-bundles}

API plans include a limited number of “regular” Bundles, allowing you to send Bundles from the Blueink Dashboard and
via the API. However, if you need to regularly send Bundles from the Dashboard and via our API, an Enterprise plan is
probably the best fit for your organization. Please contact [our sales team](https://www.blueink.com/contact-us) to
discuss options.
