How to generate carousels or graphics with Contentdrips API?

The ContentDrips API is a powerful tool for automating the creation of visually appealing carousels and single-image graphics, perfect for social media platforms like LinkedIn, Instagram, or Twitter. In a previous blog post, we covered how to set up the ContentDrips API and how it works.

In this post, we’ll dive into the specifics of preparing your carousel or graphic template to work seamlessly with the API, ensuring professional and dynamic outputs.

We’ll also explore advanced features, provide code examples, and share practical use cases to help you maximize the API’s potential.

Step 1: Understanding the Template ID

To get started with the ContentDrips API, you need a Template ID. This unique identifier links your API call to a specific template in ContentDrips. To find it:

1. Open your desired template in the ContentDrips editor.
2. Check the URL in your browser. It will look something like this:
   https://app.contentdrips.com/canvas?template=148872
   The number 148872 is your Template ID.

This ID is critical as it tells the API which template to use for rendering your carousel or graphic. Whether you’re creating a multi-slide carousel or a single quote graphic, the Template ID is the starting point.

Step 2: Preparing Your Carousel Template

Carousels are a fantastic way to share engaging, multi-slide content on platforms like LinkedIn or Instagram. To prepare a carousel template for the ContentDrips API, follow these steps:

Adding and Labeling Textboxes

Each slide in your carousel can include a heading, description, or both, along with an optional image. At least one textbox is required per slide. Here’s how to set it up:

1. Add Textboxes: In the ContentDrips editor, add textboxes to each slide for the heading and/or description.
2. Label Textboxes: Right-click on a textbox, hover over the Label option, and assign a label such as heading or description. This labeling is crucial as it allows the API to map your data to the correct text fields.
   • Example: Label one textbox as heading for the slide title and another as description for the body text.
3. Add Images: If your slide includes an image, label it as image in the editor. This ensures the API can replace it with your specified image URL.

Setting Max Height for Textboxes

To ensure your text fits perfectly without overflowing, you can set a max height for each textbox:

• Select the textbox in the editor.
• Navigate to the Spacing and Max Height option in the left menu.
• Set a maximum height. If the text exceeds this height, ContentDrips will automatically reduce the font size to fit, maintaining a clean and professional look.

This feature is especially useful for dynamic content where text length varies, such as user-generated quotes or product descriptions.

Using Auto-Layout for Text

ContentDrips offers an auto-layout text feature to prevent overlapping textboxes. If two textboxes are vertically close and one contains lengthy content, the API will automatically adjust the position of the other textbox to avoid overlap. This ensures your design remains visually appealing, even with varying content lengths.

Saving Your Template

Once you’ve added and labeled your textboxes and images, and configured any advanced settings like max height, save your template in the ContentDrips editor. It’s now ready for use with the API.

Step 3: Making the API Call for Carousels

To generate a carousel, you’ll use the ContentDrips API endpoint with the carousel-maker tool. Below is a sample API call to render a carousel:

const response = await fetch("https://generate.contentdrips.com/render?tool=carousel-maker", {
method: "POST",
headers: {
"Content-Type": "application/json",
Authorization: "Bearer YOUR_API_KEY"
},
body: JSON.stringify({
template_id: "148872",
output: "png",
carousel: {
intro_slide: {
heading: "Welcome to Our Brand",
description: "Discover how we create value for our customers.",
image: "https://example.com/intro-image.png"
},
slides: [
{
heading: "Slide 1: Our Mission",
description: "Empowering businesses with innovative solutions.",
image: "https://example.com/slide1-image.png"
},
{
heading: "Slide 2: Our Vision",
description: "Building a future where technology drives success.",
image: "https://example.com/slide2-image.png"
}
],
ending_slide: {
heading: "Join Us Today",
description: "Let’s create something amazing together!",
image: "https://example.com/ending-image.png"
}
}
})
});

If you use n8n you can also use our node. You can find it here.

Explanation of the Code

• Endpoint: https://generate.contentdrips.com/render?tool=carousel-maker specifies that you’re rendering a carousel.
• Headers: Include your API key in the Authorization header. Learn how to get your API key in our previous blog post.
• Body: The template_id links to your template, output specifies the format (png or pdf), and the carousel object contains the content for the intro slide, main slides, and ending slide.
• Output Formats: Use png for image-based carousels (ideal for Instagram) or pdf for LinkedIn carousels.

Step 4: Preparing a Single-Image Graphic Template

For single-image graphics, such as quote posts or promotional banners, you’ll use the same ContentDrips API but without the ?tool=carousel-maker parameter. Here’s how to prepare your template:

1. Add and Label Elements: Add textboxes or images to your template and label them appropriately. For example, for a quote graphic, label one textbox as quote and another as author. For an image, label it as image.
2. Use Content Updates: To dynamically update text or images, use the content_update array in your API payload.

Here’s a sample API call for a single-image graphic:

const response = await fetch("https://generate.contentdrips.com/render", {
method: "POST",
headers: {
"Content-Type": "application/json",
Authorization: "Bearer YOUR_API_KEY"
},
body: JSON.stringify({
template_id: "148873",
output: "png",
content_update: [
{
type: "textbox",
label: "quote",
value: "The only limit to our realization of tomorrow is our doubts of today."
},
{
type: "textbox",
label: "author",
value: "Franklin D. Roosevelt"
},
{
type: "image",
label: "background",
value: "https://example.com/background-image.png"
}
]
})
});

Explanation of the Code

• Endpoint: https://generate.contentdrips.com/render is used for single-image graphics.
• Content Update: The content_update array allows you to dynamically update labeled textboxes or images. Specify the type (textbox or image), the label you assigned in the editor, and the new value (text or image URL).

Step 5: Advanced Customization with Custom Labels

Beyond heading, description, and image, you can assign custom labels to textboxes or images for more flexibility. For example, if your template includes a hashtag or a call-to-action button, label it as hashtag or cta. Then, update it in the API payload:

content_update: [
{
type: "textbox",
label: "hashtag",
value: "#Branding #SocialMedia"
},
{
type: "image",
label: "cta",
value: "https://example.com/cta-button.png"
}
]

This feature is ideal for automating dynamic content like hashtags, social media handles, or branded images.
