Which Salesforce fields are updated
When to use this guide: Use this guide when configuring or validating CRM integration behavior.
When OutboundSync is connected to your Salesforce instance, it updates two groups of fields:
- Default fields on Contact, Lead, and Account that OutboundSync can populate during matching and creation.
- Custom fields on Contact, Lead, and Task that track engagement activity and sync details from your Sales Engagement Platform.
Default fields
Section titled “Default fields”Before creating custom fields, OutboundSync can backfill a set of standard Salesforce fields on Contact, Lead, and Account records. Matching uses email as the unique identifier for Contact and Lead, and domain (plus any configured account lookup fields) for Account. If a record already exists and a default field already has a value, OutboundSync does not overwrite it.
Coverage depends on what the source platform sends in the webhook payload. The Source platforms column shows which platforms supply each field today.
Default Contact fields
Section titled “Default Contact fields”| Salesforce field | Notes | Source platforms |
|---|---|---|
| Email Email Email | Used as the match key when searching for an existing Contact. | All platforms |
| First Name FirstName Text | Split from the lead’s full name. Falls back to the email local part if no name is provided. |  Smartlead  EmailBison  HeyReach |
| Last Name LastName Text | Split from the lead’s full name. Left blank if unavailable. | Smartlead EmailBison HeyReach |
| Phone Phone Phone | Populated when the source platform provides a phone number on the lead. | Smartlead |
| Title Title Text | Set from the lead’s job title when provided by the source platform. | EmailBison HeyReach |
Default Lead fields
Section titled “Default Lead fields”| Salesforce field | Notes | Source platforms |
|---|---|---|
| Email Email Email | Used as the match key when searching for an existing Lead. | All platforms |
| First Name FirstName Text | Split from the lead’s full name. Falls back to the email local part if no name is provided. | Smartlead EmailBison HeyReach |
| Last Name LastName Text | Split from the lead’s full name. Left blank if unavailable. | Smartlead EmailBison HeyReach |
| Phone Phone Phone | Populated when the source platform provides a phone number on the lead. | Smartlead |
| Company Company Text | Required on Salesforce Lead. Set from the lead’s company name; falls back to the email domain, then "Unknown Company" if neither is available. | All platforms |
| Website Website URL | Set from the lead’s company website or the email domain. | Smartlead |
| Title Title Text | Set from the lead’s job title when provided by the source platform. | EmailBison HeyReach |
Default Account fields
Section titled “Default Account fields”When a Contact is synced and no matching Account is found, OutboundSync creates one. Account matching uses the email domain plus any fields configured under accountLookupFields on the webhook.
| Salesforce field | Notes | Source platforms |
|---|---|---|
| Name Name Text | Required on Salesforce Account. Set from the lead’s company name; falls back to the email domain when unavailable. | All platforms |
| Website Website URL | Derived from the company website or email domain. | Smartlead |
Custom fields
Section titled “Custom fields”OutboundSync can also create custom fields on Contact, Lead, and Task. These fields are helpful for:
- Reporting on outbound activity.
- Triggering automation in Salesforce flows.
- Building lead and contact list views.
- Understanding campaign attribution and engagement history.
The current Salesforce custom field model is v2. Salesforce webhooks last updated on or after June 11, 2026 at 09:00 UTC use the v2 write behavior. In v2, OutboundSync creates fields based on the connected Sales Engagement Platform:
- Common fields are created for every Salesforce connection.
- Email-only fields are created for email sequencer connections.
- Social-only fields are created for social selling connections.
- Hybrid or unknown platform connections use the full field union.
Field creation is safe to rerun. OutboundSync checks whether each managed field already exists before creating it, creates only missing fields, and attaches field permissions only when they are missing. Before creating fields, OutboundSync also checks whether the connected Salesforce user has metadata permissions such as CustomizeApplication or ModifyAllData; if those permissions are missing, the create-field action returns a clear permission message.
Below is the current v2 list of all custom fields OutboundSync can create, including their field group, API names, and data types. Your Salesforce org may have a smaller subset when it is connected to only an email platform or only a social platform.

Legacy v1 custom fields
Section titled “Legacy v1 custom fields”The legacy v1 model created the same compact set of 31 custom fields for Salesforce connections. Salesforce webhooks last updated before June 11, 2026 at 09:00 UTC can continue to write the v1 fields until the webhook is updated. Existing customers may still see these labels in older orgs, automations, list views, or reports.
OutboundSync keeps these fields compatible for legacy customers. The v2 model adds channel-specific email and social fields, but it does not require existing reports or automations that use v1 fields to be removed. Because field creation only adds missing fields, any v1 field that already exists keeps its original label — it is not renamed to its v2 label.

|---|---|---|
| Last App Url | OSLastAppUrl__c | Text(255) |
