Developers
Connect customer data to messaging and survey triggers.
Use Contacts API, WhatsApp API, SMS API, and integrations to sync profiles from CRMs, spreadsheets, and internal systems, then trigger broadcasts, service messages, and surveys with current customer data.
Technical Entry Points
The developer lanes that keep profiles, messages, and triggers connected.
Each API lane is described in business terms first, then linked directly to the implementation docs engineers actually need.
WhatsApp API
Use WhatsApp for campaigns, richer notifications, and customer conversation flows.
SMS API
Use SMS for alerts, OTPs, reminders, and dependable customer communication at scale.
Contacts API
Sync customer profiles and audiences from CRMs, spreadsheets, or internal systems so messaging data stays aligned.
Integrations and webhooks
Connect SMSLeopard to products, CRMs, and workflow tools without hiding the technical path in a separate corner of the brand.
Why It Matters
Personalization only works when the profile is current.
The technical path matters because broadcasts, automations, and surveys get better when the customer profile is synced, current, and usable across systems.
Faster evaluation
Help product and engineering teams quickly understand how profile sync, segmentation, and messaging fit together before they dive into implementation.
Clear technical handoff
Move directly from commercial pages into the right docs for contacts, sending, delivery reports, and integrations.
Business and technical alignment
Keep marketing, product, engineering, and data teams aligned on the same customer engagement model instead of fragmenting the story.
