Overview
Moving from Apifon to Twenty CRM is a cross-domain migration: Apifon is a multichannel messaging platform organized around Contacts, Audience Lists, Campaigns, and channel-specific delivery metadata; Twenty CRM is an open-source CRM built around People, Companies, Opportunities, and Tasks. We map Apifon's contact-centric model to Twenty's People and Companies objects, preserve channel consent flags (SMS, Viber, Email, RCS) as custom properties on the Person record, and carry forward audience list membership as Tags. We do not migrate automation flows, landing pages, or sign-up forms as code because Apifon does not expose these via API and Twenty has its own distinct automation model. Campaign send history migrates as Activity records tied to the Person. Workflow and automation rebuild scope is delivered as written documentation for the customer's team to implement post-migration.
Every standard and custom field arrives verified.
AI proposes the map; you confirm before any record moves.
Parent–child, lookups, and ownership stay linked.
Calls, emails, meetings — with original timestamps.
Documents, uploads, and inline notes move with the record.

Object mapping
Each row shows how a Apifon object lands in Twenty CRM, including any object-level transformations, lookup resolution, or schema-design dependencies.
Typical mapping — final map is confirmed during the sample migration step.
Apifon
Contact
Twenty CRM
Person
1:1Apifon Contacts map to Twenty Persons. Phone number becomes the primary identifier (phoneNumbers field), email maps to email, name maps to displayName. Channel-specific consent flags (SMS opt-in, Viber opt-in, Email opt-in, RCS opt-in) from Apifon's metadata migrate as custom properties on the Person record. GDPR consent timestamps migrate as custom date fields. We use the email address as the dedupe key during import to prevent duplicate Person records.
Apifon
Audience List
Twenty CRM
Tag
lossyApifon Audience Lists map to Twenty Tags attached to the Person record. Each Audience List becomes a Tag with the list name as the tag name. List-level suppression rules (contacts blocked from sends) become custom boolean properties on the Person (e.g., suppress_sms, suppress_email) so that downstream automation does not silently re-import blocked contacts. We document which suppression rules existed per list during scoping.
Apifon
Campaign
Twenty CRM
Task (Activity)
1:1Apifon Campaigns (message sends) map to Twenty Task records linked to the Person. The campaign name becomes the Task title, send status (delivered, failed, opened, clicked) becomes custom Task properties, and timestamp migrates as ActivityDate. Channel designation (SMS, Viber, Email, RCS) becomes a custom picklist field on the Task. We do not migrate message content unless the API exposes template body; we document which campaigns had custom content versus template-based sends.
Apifon
Automated Flow
Twenty CRM
Sequence (manual rebuild required)
lossyApifon automated flows with smart SMS failover map to documentation, not automated migration. Twenty has Sequences for task follow-ups but the trigger-based conditional routing in Apifon has no direct equivalent. We export flow structure, trigger conditions, and step sequences as a written document with screen-captured flow diagrams where available. The customer's team rebuilds flows manually in Twenty or via n8n integration post-migration.
Apifon
Template
Twenty CRM
Email Template or Task Template (manual rebuild)
lossyApifon message templates (SMS, Viber, Email, RCS) with variable placeholders migrate as content documentation. We export template body, channel designation, and variable placeholders. Twenty does not have a native template library for SMS or Viber; Email Templates exist for outbound emails. We document which templates map to Twenty Email Templates and which require rebuilding as separate channel integrations (Twilio for SMS, native Viber for messaging).
Apifon
Sign-up Form
Twenty CRM
Documentation only
lossyApifon sign-up forms collect contacts and assign them to audiences with consent captured. The form structure, field mappings, and audience assignment rules migrate as written documentation. Form logic cannot be automated elsewhere without rebuilding. We deliver a field-map spreadsheet listing each form field, its Apifon data type, and the recommended Twenty Person field or custom property mapping.
Apifon
Analytics Events
Twenty CRM
Task custom properties
1:1Apifon campaign performance metrics (delivery rate, open rate, click rate, failure reason) migrate as custom properties on the linked Task records. Aggregate KPIs per campaign migrate as documentation noting total sends, delivery rate, and engagement rate. Individual event-level data (per-contact engagement timeline) migrates as separate Task records with event-type designation.
Apifon
Channel Configuration
Twenty CRM
Documentation only
lossyApifon channel credentials (sender IDs, Viber business account IDs, RCS configuration identifiers) are platform-specific and tied to Apifon's carrier relationships. These cannot transfer to Twenty. We document which channels were configured per contact and flag the re-authentication steps required at each carrier or messaging provider (Twilio, Vonage, MessageBird) the customer selects for ongoing messaging after migration.
Apifon
Custom Field
Twenty CRM
Custom Field on Person
1:1Apifon custom fields on Contacts extend the base schema with customer-specific properties. We export field names, data types, and all populated values. Custom fields migrate as Twenty custom fields on the Person object. Text fields map to text, number fields to number, date fields to date. Multi-select or tag-based custom fields in Apifon map to Twenty Tags attached to the Person. We pre-create the destination schema before any Person import.
Apifon
Company (if present in Apifon)
Twenty CRM
Company
1:1If Apifon contains company-level records (business name, domain, address) linked to Contacts, these map to Twenty Companies. The company name becomes the Company displayName, domain maps to the website field, and address maps to address fields. Company records are created before Person import so that the Company-Person relationship is resolved at the moment of Person insert.

Gotchas + challenges
Platform-specific issues from each side, plus the pair-specific challenges that don't show up on either platform's page on its own.
Apifon gotchas
No public API documentation detail in research data
Landing pages are not accessible via API
Pricing is opaque — no published tiers
No documented data portability tool
Smart failover logic requires manual rebuild
Twenty CRM gotchas
Import order is enforced and critical
Export limited to 20,000 records and visible columns only
Soft-deleted records count toward uniqueness and trigger restores
API rate limits cap at 200 req/min on Organization tier
No native email sequences — follow-up cadences require external tools
Pair-specific challenges
Migration approach
API discovery and data audit
We request Apifon API credentials and run a live discovery call against the Apifon API to confirm export scope for Contacts, Audience Lists, Campaigns, Templates, and Analytics data. We identify which endpoints support bulk export, pagination limits, and any field-level restrictions. We audit the source data for custom field usage, suppression rules, campaign history volume, and engagement event counts. If API access is insufficient or denied, we explore alternative data retrieval methods and document the constraint before committing to a migration timeline.
Schema design for Twenty CRM
We design the destination schema in Twenty CRM. This includes pre-creating custom fields on the Person object for channel consent flags (SMS, Viber, Email, RCS opt-in), GDPR consent timestamps, and any Apifon custom properties that do not map to standard Twenty Person fields. We configure Tags for audience list mapping and document the suppression rules that require custom boolean properties on Person. We set up Company records first to support Person-Company relationships before any Person import begins.
Sandbox migration and reconciliation
We run a full migration into a Twenty CRM sandbox environment using production-like data volume. The customer reconciles record counts (Persons in, Companies in, Tasks in), spot-checks 25-50 random Person records against the Apifon source for data accuracy, and validates that Tags correctly reflect audience list membership and suppression rules. Sign-off on schema and mapping occurs here before production migration begins.
Production migration in dependency order
We run production migration in record-dependency order: Companies first (if present), then Persons with email as the dedupe key, Tags created to reflect audience list membership, suppression flags set on blocked Persons, and Tasks created for campaign send history with channel designation and engagement metrics. Each phase emits a row-count reconciliation report before the next phase begins. We use Twenty's API for imports exceeding CSV loader capacity.
Cutover and handoff documentation
We freeze writes in Apifon during cutover, run a final delta migration for any records modified during the migration window, then enable Twenty CRM as the system of record. We deliver the automation flow documentation, template inventory, form-field mapping spreadsheet, and channel re-authentication checklist. We do not rebuild Apifon automation flows or messaging sequences inside the migration scope; that work is handled by the customer's team or a Twenty implementation partner.
Post-migration support window
We support a five-business-day hypercare window following cutover where we resolve any reconciliation issues raised by the customer's team. We validate that all Person records carry correct consent metadata and that Tags reflect the intended audience list structure. We do not provide ongoing admin support, training, or workflow rebuild as standard scope; these are separate engagements.
