Integrations questions, answered
The questions buyers ask most often before they sign.
How long does an integration take to set up?
Native connectors (Twilio, Salesforce, HubSpot, Zendesk, Stripe, Shopify) take under 15 minutes via OAuth. Custom REST or webhook integrations on Growth and Scale plans take ~1 day with our solutions team.
Can I connect a custom CRM or homegrown API?
Yes. Define a function tool with a name, description, and JSON schema for parameters. CallSphere calls your endpoint when the agent invokes the tool. Auth supports API keys, OAuth 2.0, and HMAC-signed webhooks.
Do integrations work for both voice and chat agents?
Yes. The same tool definitions, knowledge bases, and integrations are reused across voice, chat, and SMS agents. Configure once, deploy everywhere.
Is there a marketplace for integrations?
Yes -- see /marketplace for the live list. Today the marketplace covers CRM, calendar, telephony, payments, e-commerce, helpdesk, and ITSM categories.
Can I bring my own Twilio account?
Yes. Provide your Account SID and Auth Token; CallSphere routes calls through your Twilio account so you retain control of telephony billing and compliance posture.
