WordPress

Connect your WordPress site to Slate and publish AI-generated content directly to your blog or website.

The WordPress integration lets you create and update posts on your WordPress site directly from Slate workflows. Generate content with AI, upload images, and publish — all without leaving Slate.

Why connect WordPress to Slate?

Slate generates content through AI-powered workflows. WordPress powers your website. Connecting the two lets you go from content generation to published post in a single automated flow.

Prerequisites

• A Slate account with an active workspace
• A self-hosted WordPress site or WordPress.com site with REST API access
• A WordPress user account with permission to create and edit posts
• An Application Password generated from WordPress

Setup

Step 1: Generate a WordPress Application Password

1. Log in to your WordPress admin dashboard.
2. Go to Users > Profile (or click your username).
3. Scroll down to the Application Passwords section.
4. Enter a name for the password (e.g., “Slate Integration”).
5. Click Add New Application Password.
6. Copy the generated password. WordPress shows it only once.

Application Passwords require WordPress 5.6 or later. If you do not see the Application Passwords section, check that your site uses HTTPS — WordPress disables this feature on non-HTTPS sites.

Step 2: Connect WordPress in Slate

1. Open Slate and go to Administration > Integrations.
2. Find WordPress and click Connect.
3. Fill in the connection details:
   • Connection Name — A label for this connection (e.g., “Company Blog”)
   • Site URL — Your WordPress site URL (e.g., https://yoursite.com)
   • Username — Your WordPress username
   • Application Password — The password you generated in Step 1
4. Click Save.

Slate validates the credentials by calling the WordPress REST API. If the credentials are valid, the connection appears as active.

Step 3: Use the connection in a workflow

1. Open or create a workflow.
2. Add the WordPress block from the Apps section.
3. Select your WordPress connection from the dropdown.
4. Choose an action: Create Post, Update Post, or Upload Media.
5. Map your workflow data to the post fields.

What you can do

Once connected, the WordPress integration supports three actions through the workflow block:

Create Post

Add a new post to your WordPress site.

Field	Required	Description
Title	Yes	Post title
Content	Yes	Post body (HTML supported)
Slug	No	URL slug for the post
Excerpt	No	Short summary
Status	No	draft, publish, pending, or private
Author ID	No	WordPress user ID for the author
Featured Image ID	No	Media library ID for the featured image
Categories	No	Comma-separated category IDs
Tags	No	Comma-separated tag names
Post Type	No	WordPress post type (defaults to post)
Template	No	Page template file name
Meta	No	Custom fields as JSON

Update Post

Modify an existing post by matching its slug.

All fields except slug are optional. Only the fields you map are updated — everything else stays unchanged.

Upload Media

Upload an image to the WordPress media library. Three source options:

Source	Description
URL	Fetch an image from an external URL
Upload	Use a file uploaded in the workflow
Drive	Pull an image from Slate Drive

The uploaded image returns a media ID that you can use as the featured image in a Create Post or Update Post action.

Use cases

AI-powered blog publishing

Generate blog posts with the LLM block and publish them as drafts on WordPress for editorial review.

Example flow: Target keywords → LLM generates article with title, body, excerpt, and slug → WordPress block creates a draft post

Bulk content generation from a sheet

Store topic ideas or content briefs in a Slate sheet. Loop through each row, generate content, and publish to WordPress.

Example flow: Sheet with content briefs → Loop block iterates rows → LLM writes article per row → WordPress block creates draft posts

Image-rich content publishing

Generate content and images together. Upload AI-generated images to the WordPress media library, then attach them as featured images on new posts.

Example flow: LLM generates article → Generate Image block creates a featured image → WordPress block uploads media → WordPress block creates post with featured image ID

SEO landing pages at scale

Use keyword data from Semrush blocks to generate optimized landing pages and publish them to WordPress.

Example flow: Semrush keyword data → LLM writes landing page copy → WordPress block creates pages with target slug and meta

Content refresh and updates

Identify outdated posts, regenerate their content, and push updates back to WordPress using the slug to match existing posts.

Example flow: Sheet with post slugs to update → LLM rewrites content → WordPress block updates each post by slug

Multilingual content publishing

Translate content into multiple languages and publish each version as a separate post or to a multilingual plugin’s post type.

Example flow: Source content → LLM translates to target language → WordPress block creates post in language-specific category

Managing connections

View connections

Go to Administration > Integrations to see all your WordPress connections and their status.

Re-authenticate

If your Application Password is revoked or your credentials change:

1. Generate a new Application Password in WordPress.
2. Open the connection in Slate.
3. Enter the new username and password, then save.

The site URL cannot be changed when re-authenticating. To connect a different site, create a new connection.

Remove a connection

Delete a connection from Administration > Integrations. Any workflows using that connection will need to be updated with a new one.

Troubleshooting

Issue	Cause	Solution
Connection fails on save	Invalid credentials	Verify your username and Application Password are correct
”401 Unauthorized” errors	Password revoked or expired	Generate a new Application Password in WordPress
”403 Forbidden” errors	User lacks permissions	Ensure the WordPress user has Editor or Administrator role
Application Passwords section missing	Site not using HTTPS or WordPress < 5.6	Enable HTTPS on your site or update WordPress
Posts created but not visible	Status set to draft	Check the post status or change the workflow to set status to publish
Categories not applied	Wrong category IDs	Look up category IDs in WordPress under Posts > Categories
Featured image not showing	Invalid media ID	Upload the image first and use the returned media ID
Custom fields not saving	REST API access not enabled for fields	For ACF fields, enable “Show In REST API” in the field group settings
