 <h3> Background</h3>
 <p>Weave is an API aggregator for the Travel Tech industry.  Weave enables applications to integrate with a number of different service providers using a single API.  When the underlying service provider APIs change, the integrations built using Weave will be updated with minimal to no development effort by application developers.  Weave will continue to support previous versions of its own API endpoints for a predetermined period of time to enable developers sufficient time to plan and execute updates to their product roadmaps</p>
