The USPS Hold For Pickup Express Mail Label API allows developers to generate Express Mail labels and barcodes for Hold For Pickup shipments. These shipments are sent to a designated Hold For Pickup location where they can be picked up within five calendar days.
This API is part of the USPS Web Tools API library which provides access to USPS data free of charge.
The following is a list of libraries from ProgrammableWeb's Library Directory that matched your search term. Although there many different interpretations of the word "library" among software developers, ProgrammableWeb adheres to a specific definition so as to clearly distinguish libraries from SDKs and frameworks in a way that will facilitate clean search results. In ProgrammableWeb's parlance, the term "library" is strictly used to describe a platform-specific software tool that, when installed, results in the provisioning a specific API. Conversely, SDKs are exclusively for consuming APIs and Frameworks are agnostic to specific APIs. If you think a library, SDK, API, or other asset is missing from our directory, be sure to check our guidelines for making contributions to ProgrammableWeb.
