Appgain

aid: appgain
name: Appgain
description: Appgain is an omnichannel messaging and mobile marketing automation platform, originally out of the MENA region,
  that lets marketers acquire, engage, and retain mobile and web users across push notifications, in-app messaging, email,
  SMS, WhatsApp, and web push from a single cloud. Its REST API and mobile SDKs power smart deep links, micro landing pages,
  behavior-triggered automation journeys, a customer data platform (CDP) with real-time event logging and purchase tracking,
  and multi-channel campaign delivery, with marketplace apps for Shopify, Zid, and Salla and no-code integrations via Zapier
  and n8n. The backend is built on the open-source Parse Server stack, and first-party SDKs cover Android, iOS, Flutter, React
  Native, Cordova/Ionic, and web. Since 2026 the company positions itself as an "AI Workforce Platform" for MENA businesses,
  adding AI agent products - a RAG-powered customer bot, AI call intelligence with Arabic and English transcription, a visual
  bot builder, and a unified inbox - on top of the messaging core. The only machine-readable contract Appgain publishes is
  a public Postman collection served from its own apidocs subdomain; there is no OpenAPI.

x-enrichment:
  date: '2026-08-13'
  status: enriched
  artifacts_added: 17
  artifacts_updated: 6
  pass: local-v1
  headline: Contract discovery found the machine-readable contract the previous pass missed - a real public Postman Collection
    v2 (30 requests, 4 hosts) served from Appgain's own apidocs.appgain.io - plus a genuine llms.txt at www.appgain.io/llms.txt.
    There is still no OpenAPI on any host.
x-pointers-deliberately-withheld:
  note: Artifacts exist on disk for these, but no canonical scored pointer is emitted because the underlying thing is genuinely
    absent. Recorded so a later pass does not "fix" it by adding the pointer.
  withheld:
  - type: WellKnown
    reason: no /.well-known document on any of six hosts; www.appgain.io returns HTTP 200 for every /.well-known path but
      the body is the identical SPA shell, so those 200s are a catch-all, not documents
    artifact: well-known/appgain-well-known.yml
  - type: SecurityTxt
    reason: no security.txt served
    artifact: well-known/appgain-well-known.yml
  - type: AgentCard
    reason: no A2A agent card at /.well-known/agent-card.json or /.well-known/agent.json on any host; search-only artifact,
      never authored
    artifact: none
  - type: MCPServer
    reason: Appgain ships no MCP server, hosted or installable. mcp/appgain-mcp.yml is a DERIVED candidate tool list with
      deployment.mode = none; pointing MCPServer at it would credit an agent surface that does not exist
    artifact: mcp/appgain-mcp.yml
  - type: StatusPage
    reason: Appgain's own n8n guide directs integrators to status.appgain.io, but that hostname has no DNS record - a documented
      status page that does not exist is an absence
    artifact: lifecycle/appgain-lifecycle.yml
  - type: Deprecation
    reason: no deprecation policy
    no Sunset/Deprecation header support: null
    artifact: lifecycle/appgain-lifecycle.yml
  - type: Idempotency
    reason: no idempotency key, header or parameter anywhere in the published contract or docs; retrying a send re-sends the
      campaign
    artifact: conventions/appgain-conventions.yml
  - type: Security
    reason: no security.txt, no responsible-disclosure page, no bug bounty; probe-security-programs.py returned vdp=none
    artifact: none
  - type: TrustCenter
    reason: no trust centre on trust.appgain.io (no DNS), security.appgain.io, or /trust|/security|/compliance; probe returned
      trust=none
    artifact: none
  - type: Compliance
    reason: no named third-party certification published (no SOC 2, ISO 27001, PCI DSS, HIPAA, FedRAMP); only marketing compliance
      language and a standard GDPR privacy policy
    artifact: conformance/appgain-conformance.yml
  - type: AsyncAPI
    reason: no AsyncAPI document; the webhook surface is advertised in release notes with no event schema, so only Webhooks
      is emitted
    artifact: asyncapi/appgain-webhooks.yml
  - type: OAuthScopes
    reason: API-key auth only - no OAuth2 flow
    token endpoint or scope surface: null
    artifact: none
  - type: OpenAPI
    reason: no OpenAPI/Swagger on any host after probing /openapi.json, /openapi.yaml, /swagger.json, /v1/openapi.json, /api-docs,
      /swagger/v1/swagger.json across six hosts; the published machine-readable contract is a Postman collection
    artifact: postman/appgain-omnichannel.postman_collection.json
