For a sales team that relies on Zoho, your leads arrive by phone, text, and web form. But the details of those conversations most likely live somewhere else entirely. You might open a lead record, see a name and number, and have no idea the person has called more than once, what they asked about, or which campaign sent them. CallRail's Zoho integration closes that loop: every qualifying call, text, and form submission CallRail captures creates or updates a Lead in Zoho and attaches a note with what actually happened.
Before You Begin
You will need the following to set up a Zoho integration:
- A Zoho CRM account. This integration works only with Zoho CRM. It does not support Bigin, Desk, Books, or other Zoho products.
- Permission in Zoho to authorize third-party apps, typically done by OAuth.
- At least one CallRail Tracker that is actively capturing calls, texts, and/or form submissions.
Connect Your Zoho CRM Account
- In CallRail, click Settings, then select Integrations.
- Find Zoho CRM in the list of integrations and click Connect.
- Log in to your Zoho account and approve the permissions CallRail requests. CallRail only asks to read, create, and update Leads, and to create Notes. Nothing else in your Zoho account is affected by this connection.
- Select which instances will send data to Zoho. You can select any combination of calls, text messages, or completed forms.
- All three of these will be off by default, so nothing will sync to Zoho until you turn at least one on.
- Click Activate to finish connecting.
As an optional step, you can set up integration filters to limit which sources, tags, or trackers send data to Zoho.
Data
Before creating a new Lead, CallRail searches your Zoho account by phone number, then by email address, to avoid creating duplicates. If a matching Lead is found, CallRail updates it instead of creating a new one, and only fills in fields that are currently blank. A field that already has a value in Zoho is never overwritten, so if a phone number or email on an existing Lead is outdated, CallRail will not correct it.
| CallRail Data | Zoho Lead Field | Written When |
|---|---|---|
| Customer phone number | Phone | Present, and the Lead has no phone yet |
| Customer email address | Present, and the Lead has no email yet | |
| Caller first name | First Name | A full name was captured, and the Lead has no first name yet |
| Caller last name | Last Name | The Lead has no last name yet |
| First-touch marketing source | Lead Source | The Lead has no lead source yet |
CallRail does not send company, title, address, city, state, country, website, industry, lead status, lead owner, or any custom Zoho field. Only the five standard fields above are ever written, and only to the Leads module: Contacts, Deals, and Accounts are never created or updated.
Every qualifying interaction also adds a note to the Lead, so repeat callers build up a history of notes over time. Each note includes:
- The interaction type and timestamp (call, text, or form submission)
- For calls: date, duration, and whether the call was answered
- The AI call summary, when one is available
- For texts: the message text and sender number
- For forms: the form URL and the fields submitted
- Marketing attribution: source, medium, campaign, landing page, and keywords from the first touch
The note does not include the call recording, transcript, sentiment, or lead score. Recordings and transcripts stay in CallRail.
Voice Assist Calls
Calls handled by Voice Assist are supported as a lead source the same way any other call is: they create and update Leads, and the caller name and email Voice Assist collects during the conversation are included. This is a one-way connection, though. Voice Assist cannot read your Zoho account during a live call, so it cannot recognize or greet a returning caller using their existing Zoho record.
Troubleshooting
| Symptom | Likely Cause | What to Do |
|---|---|---|
| "Leads module not found in Zoho account" when activating | The Leads module could not be resolved during activation | Confirm the connecting Zoho user has the module-settings read permission and that the Leads module is enabled in Zoho |
| Notes are missing, and the integration never fully activated | The Leads module information is only stored once you activate, not at the moment you authorize | Go back and complete activation so notes have a Lead to attach to |
| The integration switches to Failed with a message to reauthorize | Zoho revoked or changed the connection's access | Reconnect your Zoho account |
| The integration switches to Failed after working for a while | Several requests to Zoho failed in a row | Reconnect, or contact CallRail support if it keeps happening |
| Nothing is reaching Zoho at all | The Calls, Texts, and Forms switches are all off, or a filter is excluding the traffic | Check that at least one interaction type is turned on and review your integration filters |
| A Lead exists but has no note | The Lead was not created successfully in Zoho, so the note step was skipped | Contact CallRail support with the date and time of the interaction |
| A Lead's phone number or email is wrong and never updates | Expected behavior: the integration only fills in blank fields and never overwrites existing values | Correct the field directly in Zoho |
| Calls are missing, but texts and forms are coming through | Calls need a phone number to qualify; texts and forms do not | Expected behavior for anonymous or blocked-number calls |
Frequently Asked Questions
Will this create duplicate Leads?
Not for the same phone number or email address. CallRail searches Zoho by phone, then by email, before creating a new Lead, and updates a match instead of creating a second one. If the same person calls from a different number and uses a different email, though, they will come through as a new Lead.
Will it overwrite data my team has already entered?
No. The integration only fills in fields that are currently blank in Zoho. If a field already has a value, CallRail leaves it alone, even if the value is out of date.
Does it work with our custom fields?
Not currently. CallRail writes five standard Lead fields: Phone, Email, First Name, Last Name, and Lead Source, plus a note. Custom field mapping is not supported today.
Can it create Contacts or Deals instead of Leads?
No, the integration writes to the Leads module only. If your process converts Leads to Contacts and Deals inside Zoho afterward, that continues to work normally.
What gets set as the Lead Source?
The marketing source of the customer's first touch, such as "google" or "facebook," rather than the word "CallRail." "CallRail" is used only when there is no attribution data available. Because of the fill-the-blanks behavior, Lead Source is only set on Leads that do not already have one.
Can Voice Assist look up a caller in Zoho during the call?
No. This integration writes into Zoho, but Voice Assist does not read Zoho during a live call. It cannot recognize or greet a returning caller based on their Zoho record.
Do we get the call recording in Zoho?
No. The note on each Lead includes the date, duration, answered status, and AI summary when available, but not a recording link or transcript. Those stay in CallRail.
