**APIs profiled:** 6

SendHub is a business text messaging platform for SMS/MMS marketing campaigns, two-way texting, appointment reminders, bulk messaging, SMS surveys, group messaging, and VoIP calling, used by more than 10,000 businesses. It exposes a REST-like v1 API at api.sendhub.com for programmatically managing contacts, groups, messages, inbox threads, account settings, and enterprise users, authenticated with a line username and API key (query params) or HTTP Basic. Published plans run Lite $19/mo to Basic $100/mo plus a quoted Custom tier, and every tier lists API access, though the developer page still says API access is custom-plan only. SendHub also supports 100+ integrations via direct connectors and Zapier plus inbound-SMS webhooks, and is a New Era Technology company. Surfaced as a 500 Global portfolio company and enriched by the API Evangelist pipeline.
