CallFire API

Overview

CallFire API is a REST interface for adding text, voice and campaign workflows to software that uses CallFire telephony. It best suits teams connecting an existing CRM, mobile app or website backend. Its broad messaging and calling tools are useful, but monthly allowances and North American coverage will determine whether it fits.

Key features

API v2 accepts requests from any HTTP client and returns JSON, so developers can work with their existing stack. CallFire also lists SDKs for Java, .NET, JavaScript, Python and PHP; the JavaScript, Python and PHP SDKs are beta, a consideration for teams building production integrations around them.

The API supports individual text and voice messages as well as text and voice broadcasts. Campaign management, scheduling controls, free call recording and real-time reporting support more involved communication programs. Contacts, number and keyword ordering, short codes, a sound library, and action states and results add tools for managing delivery and campaign outcomes. Webhooks report events such as campaign activity and incoming texts, allowing connected software to react to activity.

API v2 uses HTTP Basic Authentication with separately generated API credentials; standard CallFire UI credentials do not grant API access. CallFire says endpoint communications use HTTPS with TLS and webhook calls use SSL certificates. It also describes compliance solutions, including Do Not Call list management. Its API features include 24/7 support through the support page, and CallFire advertises 99.95% uptime and messaging from one contact up to one million.

Pricing

Pay as you go costs nothing, with no monthly fee. It includes optional monthly rentals, with phone numbers at $10.00 and keywords at $25. This is the lowest-commitment way to start, but the account still runs on an allowance: calls and texts stop when it reaches zero, and extra credits cost 6¢ per credit.

Lite is $99 a month and includes 2,500 minutes/texts, optional monthly rentals, $2.50 phone numbers and $20 keywords. Startup is $199 a month for 5,500 minutes/texts, with $2.25 phone numbers and $15 keywords. These plans suit teams that need a defined monthly allowance and regular number or keyword rentals, with Startup providing more usage at a higher monthly price.

Grow is $299 a month and includes 10,000 minutes/texts, optional monthly rentals, $2.00 phone numbers and $13 keywords. Pro is $599 a month for 20,000 minutes/texts, optional monthly rentals, $1.75 phone numbers and $10 keywords. The larger plans offer progressively more usage and lower number and keyword charges, making them the relevant tiers for higher-volume programs; users should match the allowance to expected traffic because service stops at zero unless credits are added.

Plans include calls to the US and Canada, while international text messages are not currently supported. That makes CallFire a poor fit for campaigns that depend on international texting. Pricing starts at 1 /mo; inbound and outbound calling, phone number support and call recording are supported.

Platforms

CallFire API is available on api. Its HTTP client compatibility and SDK options provide ways to integrate it with CRM platforms, mobile apps and website backends.

Who it's for

CallFire API is a strong fit for developers building text and voice communications into an existing product, especially when they need broadcasts, campaign controls, event notifications and call recording together. Teams should be comfortable generating separate API credentials and should check that the applicable usage allowance and US-and-Canada call coverage match their needs.

Pros and cons

• Pros: One API covers individual and broadcast messaging across both text and voice, plus campaign management, scheduling and real-time reporting.
• Pros: Webhooks can notify applications about campaign events and incoming texts, while multiple SDKs and support for any HTTP client leave integration options open.
• Pros: Free call recording and Do Not Call list management address useful operational needs within communications workflows.
• Cons: Calls and texts stop when the account allowance is depleted; continued use requires purchasing credits at 6¢ per credit.
• Cons: International text messages are unsupported, limiting its fit for globally distributed texting.
• Cons: JavaScript, Python and PHP SDKs are beta, and API access requires credentials generated separately from standard UI login details.

Alternatives

For a broader directory of voice-focused tools, browse Voice Broadcasting Software.

Choose CallHub if a free plan and free trial are priorities; it supports Android, iOS, macOS, web and Windows as well as API access. Text-Em-All (formerly Call-Em-All) is another option for those who want a free starting tier, including 25 credits for testing voice broadcasts and test texting to their own number; mass texting requires an upgrade.

Newfies-Dialer may suit teams seeking a self-hosted option, with API and web access and paid port plans that specify agent, tenant and daily call and SMS allowances. Consider TexTalk Voice Notification, Vasudev Voice Broadcasting, BBOX Voice Messaging, IVR Lab Automated Voice Broadcasting or Voice Broadcasting Platform when comparing other paid voice broadcasting options.

Verdict

Choose CallFire API if you need to embed text and voice messaging, broadcasts and campaign event notifications into an existing application, and your expected usage fits its allowances. Its integrated capabilities and flexible HTTP access are compelling for North American communications workflows. Look elsewhere if international texting is essential or if beta SDKs and allowance-based service interruption are unacceptable.
