Who makes this SDK, and the open-source work it stands on.
Conceptualize
Created and maintained by
Conceptualize designed and built conceptlz/adobe-sign,
conceptlz/adobe-sign-laravel and conceptlz/adobe-sign-symfony, and continues to maintain all three: releases, fixes, testing against
real Acrobat Sign accounts, and this documentation. The packages are published on GitHub under the
conceptlz organisation and released under the MIT License.
What maintenance means here
- Design & developmentThe SDK's architecture: PSR-only core, data-centre routing, retries, ETags, typed exceptions, builders, signature levels and evidence, the Laravel bridge and the Symfony bundle.
- VerificationEvery request in the test suite is validated against Adobe's published API specification, and behaviour is checked against a real Acrobat Sign account. Differences from the specification are fixed in the SDK and documented.
- ReleasesAll three packages share one version number and are released together, with a changelog for every version.
- DocumentationThese sites, the READMEs and the runnable examples, kept in step with the code.
- SupportBug reports and feature requests through GitHub issues; security reports and other enquiries by email.
